Girls - My ex wants me back, how should I react?

Some ways yes, Some ways no. I don;t really think you should get back together. The reason being because if it was bad enough to break up in the first place then it won't change. All things happen for a reason and I don't think it is going to work out. You need to just tell her that it wasn't working out and that she has great qualities that the next guy will love. But if you do choose her....then that's your choice. Good luck:)
