Advice????

Jamie
My fiancé and I have been off and on for 3 years. We have lived together for over a year and we decided a couple months ago to really start trying to have a baby. But our relationship is still very some timey... One day we may be the happiest couple in the world the next day we are fighting and he kicks me out of the house we are living in. By the time I get to my parents house which is about 15 minutes away he calls crying wanting me to come back home. (This was just last night) he always accuses me of cheating when I don't even talk to my female friends much less my male friends. He also told me he doesn't want to marry me. Again, this was all last night... Today he is asking me to show him what I found for ideas for the wedding (over a year away) what do I do? Stick with it even though it's been the same stuff for 3 years. Or move on and find somebody that won't be the way he is toward me and not kick me out every other day. Any advice??
