Wow, I must be in the 1% minority here! Brian and I never had any troubles while living together. It was (and is) a great experience for us. We always help each other out and have done so since the beginning. 7-1/2 years we are together now.
I've never had the "loser boyfriend" thing with him. We always managed to work things out.

I know most people on here think that it's bad to live with your boyfriend when you first move out of your parent's house, but I did it with no problems! (Maybe there's something wrong with us?!)
