So my boyfriend and I had an argument at the beginning of September, and we broke up. We broke up because he kept hiding things and lying. He didn't have anywhere else to go and I let him stay at the apartment to get his shit together. He never stopped sleeping in my bed, and we ended up working things out. Problem is, apparently he started talking to this girl while it was going on so wtf. They were flirty and whatever, and she's obviously into him and he knows it but for some reason keeps trying to play dumb and tell me he's not into her🙄 she keeps heart reacting to the relationship-y and sexual memes he posts on Facebook and literally 2 days ago commented on one of his posts that he should add her on snap. He never did but I've told him multiple times I'm not comfortable with her because of how their 'relationship' began, and even though he hasn't pm'd her their still active on each other's fb. Plus the way he complimented her was so much sweeter and more detailed than any compliment I've gotten. We had an argument about it last night because of a meme she heart reacted to like 2 minutes after he posted it, something about 'when you and babe fuck each other to dehydration' and I asked him why she felt comfortable doing that. He flipped shit and kept telling me it's nothing they aren't even talking and he just "likes the attention" I told him Idc, I'm not comfortable with it and she needs to be gone. It's not like she's some longtime friend, she's literally just someone he started talking to as a rebound less than a month ago. So aitbf for telling him to delete her? UPDATE: He almost killed me when I tried to talk to him. He's gone I'm ok🤷
