Can someone give me advice?

The answer is pretty obvious.....either now or later. The later the worse its going to get. If you really want to work it out with here however, you need to give her an ultimatum. You cared enough to move across country so she can be happy, if she's going to give you the same devotion, she doesn't deserve you, you can find better and she needs to know that. If she really cares about you, she'll listen. If she doesn't listen, its time to step. No point in trying if you're the ONLY one trying.
