So here is the thing we all use to hangout together before this and now I have started dating her. She has also bonded well with one of my roommate and now they had fight and both of them don’t want to see each other’s face. My girlfriend Says you should not talk to him as he has misbehaved with me, I told her you both had and argument solve it like matures, she said “I wasn’t wrong so I am not gonna say sorry to him” I said okay don’t talk to him but she says she should also not talk to him as he misbehaved but I was there they just had a simple argument and both of them are having an ego issue that I wasn’t wrong so why should I say sorry. My friend said after that issue I am not talking to her and other roommates also doesn’t like her you have your relationship with her at whatever place you like we doesn’t want her here at our place. I said no she would come cause it’s my place as well. Now in this situation I am having this issue that I am wrong in both of their mind. Please help me how can I fix it or i am wrong in here in way or how to deal with such situation.
