It's my first time posting on here but I am kinda here to just lay out all the events and I really need to know if I'm wrong and

I (22F) have a coworker/friend whom I've worked with for a while lets call her K (26F). She also has a brother who works in the same field let's call him L (22M). I developed a crush on L a year after we met and I think he's a pretty great guy. Our chats are never awkward and we have very similar jokes and humor. He is a really good listener and pays attention to small details. He's remembered my favorite foods and smells (I am kinda perfume obsessed) and even copies my lingo.

I have never told anyone and never really planned to confess since K confided in me that his last relationship was extremely toxic and his ex continues to harass their family and spread nasty rumors to anyone who will listen and send L hate through texts, emails, and basically any way possible. I kinda just figured he wasn't ready for a relationship and that he was just being nice.

Until we had a company potluck and I had brought a dessert and me and another coworker, let call him J (46M) were prepping the kitchen. L came in and offered to help and J agreed. We set up everything and J mentioned that my dessert looked delicious and he could not wait to have some. I thanked him and told him he could have some now since I had brought plenty. L then was suddenly very insistent on getting the first piece. J and I looked at each other and J was told him that he didn't care who got the first piece. So I gave it to L and he told me that it tasted amazing and that I would make a great wife someday. This was the first time I every heard L say anything like that. J and I laughed because it was kinda unexpected and L left to go share some with K. J then told me that L was really not hiding his feelings. I definitely looked confused because he then told me that L very obviously had feelings for me. I denied it and told him that there was no way and J then told me that L definitely did and that no man would say that to a woman if they weren't thinking about them in that way.

That day kinda gave me hope and I tried to be more obvious with my feelings since I'm not very expressive verbally and facially. But the next week I got into a terrible wreck and was out on medical leave for 3 months. The whole time I was out L and K would constantly check on me and how I was doing in and L would even drop by my house and bring me food and hang out which really convinced me that L had feelings for me.

But after I recovered and returned to work, I found out that L was dating a newer coworker, M (24F) who had started working while was was out. J had been talking to me about work related things and M walks into the room. J then goes to hug her and he introduces us and then blurts that M is L dating and that they were so cute together. I was was completely devastated and didn't even know how to react. I just congratulated M and then fake sneezed 5 times to make it seem like my tears were from sneezing and then excused myself for a tissue.

I felt betrayed and upset at K and L for not telling me especially since they were updating me on the all the station gossip and I thought we were close enough to tell each other things. But I choose not to let my feelings ruin our work dynamic and friendship and that they had their reasons to withhold information from me. I never told K and L that their actions hurt me and I eventually forgave them after a couple of months. I never asked L how he started dating M and kinda distanced myself from him since he now had a gf and I wanted to respect their relationship.

After some time had passed. M eventually "quit" her job (she left before she could get fired) and L changed departments. At some point K and I were working on a project together and K mentions that L has been annoying her and being a little brat.

I say tell me everything and she tells me that L and M have moved in together along with M's best friend. K then tell me that she found out from L's friend that M and her best friend haven't had a stable job and L had been paying for groceries and rent for all of them which was a lot of money. She also tells me that L has been paying for M whenever they go out on dates and with friends. K is frustrated that L had been doing all this for her and that L is letting himself be taken advantage of. K holds a lot of anger towards M because M comes from a well off family and her parents send her money for her living expenses but has not contributed to for rent and groceries.

It doesn't get any better. Two months after that conversation K tells me that M tried to baby trap L and that M really wanted to have a child with L because one of M's friends is expecting. Apperantly L told his mother and his mother told him that he needed to break things off with M because this was not normal and that M might have some undiagnosed mental illness and needed to be treated by a medical professional. L tried to break it off with M and M threatens to kill L's cat and then kill herself if L every leaves her.

A couple months after that, K visits L and M's apartment. L tries to break up with M again with K as moral support and M threatens to tell the police that L sexually assaulted her and L argues that M is really not making him feel safe and M has a panic attack so bad to where she needs to be taken to the emergency room. K and L find out that M has bipolar disorder and just never told L. This really explains her behavior and the doctors recommended medication to her and M declines.

And the most recent event, is M pressuring L to propose because M's friend is now engaged. L doesn't feel eeady and really does not want to get married but he is afraid that M might actually go through with her threats and since most of them were verbal threats he has no physical evidence. It would basically be his word vs hers.

All of this Is information told to me by K. I'm happy that she feels comfortable enough to rant all of her problems to me, but I am also worried for her because this is becoming a real stressful situation for her and her family. At this point, I am really bothered because I still consider L to be a good friend even though her kinda drifted apart and deep down I still have feelings for L.

I jokingly tell her that we need to break them up because M is really toxic and who knows when she might actually baby trap him and he'll be catering to her and the child for the next 18 years.

K gets really excited at this idea and starts planning different ways to break them up and says she'll text me if any of them seem possible. I didn't think that K would take me seriously and I guess I just got excited at the fact that L might end up single again and that I might stupidly have a chance again.

We end up texting for into the night and we came up with the idea of hiring different people to give M "signs" that she is dating the wrong man. M is a very spiritual person apparently so the situation ike a "random person" giving her a "palm reading" or a "random person" telling her that her aura is negative due to her relationship would realy make her break up with L. This conversation goes on until the weekend.

During the weekend, I ended up going our with a couple of friends to a restaurant and we are all hanging out having a good time. K texts me during this about our plan and how she's gonna get a woman off craigslist to help. I take some time reading the text because it was kinda long and one of my friends, B (23F) asks me who was taking all my attention. I then tell her that me and K are planning to break L and his gf up and that K and I are really excited.

B knows that I used to have a crush on L and that I have given up on my feelings for him. B gives a weird look and asks me why I would be excited about that. I tell her that L is in a really toxic relationship and we don't want L to be miserable and eventually get baby trapped. I tried to limit the details when I explained to her what happened because a lot of it was not really for me to share.

B then tells me that I should stop trying to interfere with someone else's relationship and that it's not right that I even get involved. B tells me that they should work out their own problems and me trying to break them up is childish, selfish and kinda assholey. B also says that the only reason I agreed to this was to get L single again so I could get together with him. I told her that she entirely wrong and that all we want to do is help him get out of a toxic relationship. She's tell me that it's not my place even if that was the case. I kinda just laugh and tell her that she's right so we don't get the whole table involved and we go about our night.

I have no idea what to do now. I really want to help K with her plan to break L and M up. Not because of my romantic feelings for L but because before these feelings L was and still is my friend. Above everything I truly want L to be happy. I understand that the only connection I have with K and L is that of a coworker and friend and that I am not family but I want to help. Would I be the AH if i still went through with K's plan or should I just not get involved.

Sorry if this is kinda rushed and that the spelling is horrible but I am writing this from my breakroom
