Hey! I know how you feel, I broke up with my ex boyfriend like a month ago, and were still "friends" and every time he talks about his new girlfriend I feel bad, but I just don't let him know, And every time I talk about my new boyfriend he gets mad......I guess we still have feelings for each other, but thats a different story.(lol) Just talk to her about getting back together, If she say no then don't push it, just let it go! You never know she might come around later, but by then you might have a girlfriend and will be over her!
I hope I helped
