Wish someone would tell me what to do

My fiance and I are getting married this summer. We recently bought a house but it is in his name only. My credit was bad and he refused to put me on the deed. The other day I bought stuff for the house and he told me I had to ask if I could hang the stuff up. Then next day I find lortabs that he was hiding from me. Super Bowl sunday his drunk friend told me he was surprised we were engaged because my fiance is always saying how crazy I am. I just dont know what to do. I have invested so much time and love into this relationship and dont want to lose anything. He says he loves me but sure doesnt act like it.. anything would help.
