That sounds like a fucked up situation

Bingo! That's why living together before marriage screws up commitment. There's no attachment to each other, so if a breakup happens, someone is going to get the short end of the stick, and usually in a major financial way. It's even worse when buying a house and you're not a married couple. I'm glad at least ONE young person here seems to get it.

It depends on the situation; if you're the one who moved into your boyfriend's apartment, for example, then I'd expect you to leave, because it was his home first. However, if you got an apartment together, you'd have to come to a mutual agreement of who was going to leave.
