Hmm, one cannot have love with lust I suppose. The never ending tale of love and yearning for more. Be thankful for who you're with. Don't be so ungreatful and take her love for granted. "Snap out of it man!" as Sean Connery might say.
I'd say stop the texting and and plan some more one on one along time with your girlfriend. This 'chick' is gonna be the biggest mistake you could have. Goodluck
