How do I get him to move cross country with me?

The first post said that if a man loves you he will move mountains to get to you, etc. That is true to a degree, but there is so much you have not told us. If this guy has a good job or is in school, then of course he would be hesitant to move, I mean you are his GF, not his wife. It also depends on WHY you are moving cross country. If I was dating a woman and she suddenly said she wanted to move and couldn't give me a good reason why, I might have second thoughts about whether I wanted to be with her at all. Good luck with this.
