Okay so for context I (15F) and my ex bsf (16F) lets call her Emily, were friends for about a two years. We hung out a lot and spent a lot of time outside of school either hanging out or talking all day over the phone (texting, facetime). She got with a guy named Jack, and they were together for a few months, due to that Emily, Jack (18M) , Mike (Jack's best friend, 17M) and I would hang out sometimes. We all went to the same school so we would see them regularly as well. We all started going to a youth group together as well, so spending at least two nights together a week. Emily, Jack and Mike went to an event together one night where Jack had basically tried to abandoned Emily because of a fight but Mike noticed that and didn't let Jack do that. Emily then started telling me that she was thinking of leaving Jack and I encouraged it due to the mistreatment. I had no clue at the time but Emily and Mike started talking and he also had feelings for her and was convincing her to leave Mike as well. She ended up leaving Jack and getting with Mike right after. I was a constant thirds wheel and almost like relationship consul for them. They would fight and come to me to ask for advice and often when they had conflicts it was stemming from Emily being overly controlling or Mike being "to busy" for Emily. Which I tried to never took sides on, I would always recommend a healthy way to talk it out, personal journaling and breaking down the problem them selves to see the true problems rather than the triggers (using therapy techniques I had learned, basically). As the relationship continued (pass 6 months), she began to say things like she was bored of him and started to crush on another guy at school. I felt hurt for Mike at this point as it seemed my friend was playing the field (which I don't have a problem with, if your not in a monogamous/committed relationship) but Mike had no idea that this was how she felt. I kept telling Emily she needs to talk to Mike about this and not me. She seemed to get mad when I didn't approve her desires to cheat which made me kind of lose respect for her.

By the end of their relationship, I had noticed Mike was also losing interest as we also became close and considering him a friend and he would tell me about how Emily was just treating him worse not only in front of me but what was going in the background too. Nothing physical but it was just her being an ass like straight up ignoring him and also texting the guy she told me she had a crushing on in front of him (he didn't know, but he had a feeling something was going on). At this point I think Mike gave up and even started to show signs that he was interested in me that I didn't realize.

Signs like this: Emily, Mike and I were at an ice cream shop and while Emily went to the bathroom he asked to try my ice cream, I told him only if he gets a new spoon as he had already ate off his and I ate off mine so I didn't want it to cross contaminate situation. He was playfully bantering about it not mattering but finally decided that he would just get a new spoon and as he got up he said really quietly "only for you" and then he winked at me while getting the spoon and then sat back down with a smile and tried my ice cream. I tried to play normal the reset of the night and was coming up with a way to talk to Emily about the interaction. After about a week a few more moments like that with more or less obvious signs, that still weren't crossing the big line but crossing a line, I decided the sooner he talk happens the better.

We were hanging out alone one day with out Mike and were out at a park, I thought this was best as it wasn't a crowded public place but wasn't mine or her house so neither of us would feel trapped if it got heated. When I told her all of the moments that had happened and how they made me feel like maybe Mike was trying something, she laughed and said that I was delusional (I believe this is because I am a heavier girl and she is practically the beauty standard socially right now) which just made me feel worse about this friendship. I then noticed every time Emily, Mike and I hung out after that she would yell at him for getting to physically close to me or for us talking to much about anything. She was only like this for like a week or two before she officially broke it off with Mike and immediately started dating that other guy she had a crush on.

I remained talking to both and helped Mike through his break up. As in being there for him to talk his feelings out with and recommending ways to get over her in an healthy way. Emily and I were still friends but she slowly stopped talking to me for a bit and I thought it was because I was still friends with Mike but found out later that her new bf was controlling and basically made her disconnect from all her current friends to only be friends with his friends. Mike and I got close during this time and he hadn't really showed interest in me like before for a couple of months. After those months, he started making it very obvious, asking me about my dating life and who I was talking to, even if he didn't know them he would tell me he was better. I forced myself into thinking it was nothing as my friends words kept floating back to me.

Mike got sick of dropping hints one day and told me straight up he liked me and wanted to give it a shot, I said no as I would hate to hurt Emily and that would make us look really bad. I had also developed strong feelings for Mike at this point but didn't want to act on it. He tried convincing me for months and we even kissed twice as I did break once. We have never officially dated but am I AITAH?

can add updates, if enough interested is shown. also the ages shown is what we were in the beginning not now.
