I have two flatmates, had an argument with one of them, she was very wrong, I decided I couldn’t continue being friends with her. My boyfriend comes over to my place sometimes, he knows about the situation but still he would be asking me about the girl and talking to her, like why are you asking me about someone I’m not cool with, talk to her if you want to, don’t ask me about her. I told him to stop cause it makes me uncomfortable but he hasn’t stopped. Anyways, he’s no longer welcome since he doesn’t have boundaries and is making me uncomfortable in my own house.
