I forgot to add:
Last time I was in a crisis house, a counselor there told me this:

It is better to be respected than loved. If someone doesn't love you, but respects you, that is acceptable (i.e. doctors, coworkers, etc.) Not everyone is going to love you. But for someone to love you, but not respect you...the relationship isn't healthy.

I believe my fiance is in that last category. I do think he loves me, but he doesn't respect me.
