No I can assure you it isn't, half baked ideas, and pressuring you to move at a point when your just getting stable sounds almost self destructive. It is possible for a man to be able to sit down and talk things through and build and plan something that would be beneficial to you both. That would offer a compromise, and I will be honest a wedding is a large financial drain that you might just end up resenting.

If he can give you good solid examples of his plans when you move, proof of waiting employment and an affordable home, then perhaps you would have something to discuss. Right now it sounds like, without any other focus in his life he is fixating on this marriage as his big accomplishment.
Trust your instincts, I think deep down you know if you were sure this wedding was the thing to do you wouldn't need confirmation. I am not saying chuck it all in, although it sounds you may now be travelling seperate roads. Without some very serious soul searching I suspect you will wind up wishing you could turn back the clock.
All the best. I hope whatever happens things work out for the best.
