I have been going out with my girl for about 7 weeks. She's been great and is a real tom-boy/edgey punk (but a softie). Latetly she hasn't been talking to me alot and has been hitting on my friend a bit. It's gone a bit too far and I'm starting to get a bit pissed, I've been wanting to dump her but I am not sure. Any tips, I do have a backup plan.
