I'm going through that issue right now. My boyfriend and I bought a house together back in May. Thankfully the mortgage is in his name only. He turned into like a different person once we got the house. It's kind of hard to explain. And all of his annoying habits which only bothered me a little bit before, bug me a lot since we're literally together all the time now (we work together too ). I have issues on talking about my feelings so back in July, I wrote him a letter about what I was feeling. He wrote a letter back and basically made all this promises which he has yet to uphold. Then in the middle of August, I decided that I had enough and was going to move out. I had my dad come over with a trailer and everything and at the last minute I just couldn't do that to him because I thought it would be a financial burden on him. I again reiterated the stuff I had put in the letter before that was bothering me (constantly telling lies, etc) and figured I'd give him one last chance to change. 5 weeks later and nothing has changed. I've decided I'm breaking up with him next Friday. I couldn't do it this weekend because we work. I just can't handle being this unhappy for any longer.

I think I would definitely live with someone now before marrying them. Even with dating for over a year before we got the house, there was still so much I learned about him after living together. Stuff that I know I can't live the rest of my life standing.
