Wow - he sounds like a selfish SOB. So it is OK for him to have your apt keys - what if he loses them, and your apt gets robbed - think of the problems then! Ok I'm exaggerating but you could have come up with the same excuses when giving him your apt keys.
From your little anecdote, I don't trust this guy very much. It makes me wonder how much he will be willing to share after the marriage.
It is his car, not his life that you asking for. I could understand that if he has to drive back and forth to work and you cannot drop/pick him up for some reason.
