So I'vebeen dating my bf for 4 years. I'min my second year of college and he's in his first. I wanted us to move together this year but he wanted the college dorm experience and we live in the same dorm so I was fine with it for this year. But next year we want to move together. He has a sister and their parents gave them an apartment in this city in case they don'twant to live in the dorm anymore. They want us to all live there together (me,my bf,his sister and her bf) next year. The problem is that I'm not close to his sister. We bpth spent a lot of time together and we just don't vibe in a friendship kind of way but we are always polite and respectful bc we consider each other family. The other problem is that I don't like her boyfriend at all, he talks shit about everyone, gets easily annoyed and is just a bad person in my opinion. His parents won't let us stay somewhere else and pay rent and we can't afford to buy an apartment of our own. So what should I do?(btw my bf knows all these things we already talked about it,but he keeps saying that we'll talk about this later when the college year comes to an end)
