AITA: I (F19) told my bf(M21) im uncomfortable with him hanging out with my older sister’s (F21) bf (M22/23).

I’m going to try to sum it up but here’s a little background on my sisters boyfriend. When we all first met, which was 2023, he had started working with us. I treated him as every other employee yet he came to me saying he thought I had a crush on him. I told him I didn’t as I’m a very outgoing person so I would’ve told him if I did. Shortly after he starts dating my sister which is no problem! During their relationship however he started to send weird texts inquiring about how many people I’ve slept with, my relationship, my past relationships, etc. i didn’t really go into depth with answering or sometimes I’d skip over them. Until one day i asked him for medicine since he was with my sister and she wasn’t answering (she told me she was going over his house). He then responded he didn’t have any and that i could take a hug as temporary medicine which was sent in vanishing mode… a month later he then voiced his opinion On clothes i should or shouldn’t wear…. All of this was 2023 which they ended up breaking up for other reasons.

Jump to the present day

Now they are getting back together. On Sunday, Him and my bf came over My family’s house and my current boyfriend gave him a ride back home. During the ride my sisters boyfriend requested they smoked and talked. The conversations consisted of him and my sisters past relationship, his future intentions, background on him, etc etc. I was then mentioned in this convo. He stated how he didn’t like my past bf and that my current one seemed much cooler. When my bf told me all of this i immediately raised an eyebrow.

As i was looking on my bfs phone i seen a text that my bf asked him if he could check to see if i was home whenever he got to our house. Which he did and also told him what i was doing. Which i found creepy since my door was shut and i had my tv up loud. (I was talking on the phone before anyone assumed lol.. my and my bf also argued, and i wasn’t speaking to him at the moment, which is why he asked him to do this.) after seeing the text i expressed to my bf that i was uncomfortable with how close they were getting after only knowing about each other for 14 hours…

I thought i made it clear to him and he said he understood however…he is hanging out with him even after expressing my feelings yesterday.

I’m not trying to control them or anything but i feel like my sisters bf texting my bf every day since Sunday and basically trying to hang every day since then is kind of thirsty and i have a bad feeling about it. Ive never said they couldn’t be cordial i did ask if he could refrain from 1 on 1 hangouts however. I understand he can’t avoid him in group settings but i feel like 1 on 1 is too much and very much an open door for drama.

I also have had recent and reoccurring issues with my bf not respecting me and what im comfortable with… even though i always try my best to or do always accommodate with him and his comfort.

So now im asking what should i do?

Any questions can be put in the comments, ill do my best to respond quickly!

UPDATE: My bf knows all of this yet still hung out with him. So he isn’t in the dark! And this wouldn’t be his first time hanging with people who I say make me uncomfortable (which at the end always leads to drama between him and the person and I always end up right about their intentions…)
