Kak, you've got way too much estrogen in your system.
If you were important in this chicks life, she would have made you a priority. Instead, she left to go away. Either she'll dump you completely or she'll fuck every thing in her new town and keep you on the backburner as her safety net.
She doesn't respect you. I'll say it again. She doesn't respect you. She never will. And I guaretee that when you dump her and NEVER call her again, she'll call you to get you back. You'll be tempted, but remember. SHE WILL NEVER RESPECT YOU.
Accept that it's over. Think fondly of your time together. Move on and never look back. Your life doesn't revolve around this chick and this isn't the only woman you'll ever be happy with. Especially, since she DOESN"T RESPECT YOU.
I do feel your pain. But you have to do what's best for you, not her.
