Time my friend. Time. There is no forgetting her so drop that idea but there are things you can do to make it a little easier. Big thing is to keep yourself busy and get out there with friends. You will find yourself thinking about her a lot when you have some down time for the first while. But as the weeks pass you will find yourself thinking about her less frequently. Forget. Never, but it will get easier. Good luck to you.
Oh wow. That's always the worst. When it ends not because of the two of you, but because of the situation. My last girlfriend (2 years) was French and is back in France now! Bla! Still calls to say she loves me. Its a mind f***. Go out with your friends and dance with some other girls. Having a lot of fun with other girls can help a bit.
I honestly haven't figured out the trick about how to stop loving her though haha
