<human>: We've been dating for two years and he's been living with my roommate and I for about a year now. This sort of unidealistic living situation has been an awesome and safe trial run before serious cohabitation. Everything has been going great. We never fight and if we do have a problem we can always talk it out. 

We planned on moving in together once this lease was up but something came up with his living situation so he moved into our place. The lease is ending soon and I told him well in advance that I didn't want to sign a lease to a new place with him if we weren't engaged. He always says he wants to get married and that I'm the one but no ring.

I brought up the engagement-before-move-in thing a couple of days ago and he's pissed. As I said before I told him I will not sign a lease with him without an engagement ring. He keeps saying that he can't believe I'm throwing our relationship away over something like this. I feel like if I'm going to make that kind of commitment to him that he needs to start backing up all the stuff he's been saying to me. I'm in my late 20's now. I not waiting around forever for him to really make up his mind. I could wait a lot longer if were younger but I'm 27 and he's 35.

So should I just move in with him or stick to my guns on this one?
