My girl friend told me she has to move school but I can't get her out of my head and if she moves she will probably find someone new help me

Why don't you go visit her? It would be nice... Don't let her go if she is worth it if you both love each other then nothing will come in your way :)

You will still be able to see her! Don't stress! If she's worth it don't let her go!

If she loves you, she wouldn't think of finding someone new, nothing like that will cross her mind. Have faith and trust in her..
Of course she is going to met new people that expected of her when u move schools..
But if you love her don't let her go, and if something does happened, fight for her. Show her it doesn't matter if your not together all the time, you still love her,
Go and visit to show that u still have time for her.

If she finds someone else, she would have done the same thing at your school, if she does, then you find someone else. But she most likely is thinking the same thing, as soon as she is gone, you find someone else.
