My housemate brings her boyfriend over
I have 3 housemates and A has a boyfriend. When he comes, he usually brings his housemate over. And that housemate is starting to have a relationship with my B housemate. At first, we had fun and got to know each other a bit. But recently, they are coming over too often and usually stay past midnight. B stays in the living room and of course, her boyfriend-to-be remains in the living room with her.
Last night, we had a conversation about this matter. I told A that I don't really feel comfortable when they come too often and stay too late. I wish they can come only 2-3 times a week and don't stay too late. And I asked if she can let me know ahead if her bf coming over. They refused to let me know ahead but promised to low their voice down and they will still come whenever they want. A's bf even said I just own my room which I pay and partial of kitchen and bathroom. A's bf even insulted me by comparing me with his housemate who he really hates.
Frankly, I don't feel comfortable when there are boys around. I don't know the boys that much and I don't want to remain in my room forever when they come over. If I can't stop them coming, I think I can only go to study room or stop acknowledging their presence but that may hurt my relationships with other housemates which I don't ever want it to happen. A housemate said that recently, I started to distance myself out of the group. I kept telling them that it's just the way I am but they expected me to be friendly and open to them.
