heya,
i agree with Cathryn, its hard enough having a long distance relationship, but then is it worth the travelling? Think about it after a 12 hour shift having to drive another hour n a half?

It seems you both want different things from your life, which is fine and your relationship could work out fine, but i think you need to sit down and have a talk with him and make up your mind. Its your life after all, do you think he would drive an hour n a half to go to work if you moved elsewhere and he came with?

Hope it all works out
