Some good points here, not sure it's a huge deal and I'm sure it's not that uncommon. We haven't been dating that long and she hasn't asked me yet but I think it's coming and by the time it'd be a good thought, we'd of been together for 8-9 months. Neither one of us have any plans of ever getting remarried but the whole live in thing was mentioned at best. I would never move in rent free even if she said so, I'd take care of my share, maybe not half of everything as I'd have no interest in the house.
