Re: Should I stay with her?
Personally, I don't see much point in sitting around waiting to see if your girlfriend is going to decide to get back together with you. If a boyfriend wrote that to me, I'd say "All right, well you let me know." Then I'd get out and party and whoop it up and do as I please.
If you reeeaaally want to be with her and are perfectly willing to wait, then wait. Maybe you can work things out. But if she isn't sure how she feels by now...there is no guarantee that things will work out in the long run even if you do get back together. Honestly, you guys are young and it just may not be what you need, even if it doesn't look that way right now. But I hope things work out for you.
The grass is always greener on the other side...until you get closer and see that it's astroturf~
