Is It Really Fair???

Okay, I'm the one who has been having problems with the ex-fiancee' issue. I just talked to him today and he said he was going to TX for Christmas to be with some of his family down there. Here's the thing, though. He said he's going to be down there for a while because he wants to help his cousin with his business for a while and then get a place and he wants us to get married and move down there. A part of me wants to, but then again, I've been livin in KS all my life. I'm kind of scared. I want to get out of my dad's house. I'm 23. I do believe it's time to make a life of my own. I feel I need to get out of my comfort zone as well and this may be the only way to do that. But I am a little weary of struggling with him as far as finances and things go. I know you all can't tell me exactly what to do because it's ultimately my decision, but do you all think this is a good decision?
