What do you do when you broke up with someone and you both still love each other but she is with someone else and you want her back?

I have no idea if it was your choice to break-off with your ex or not, but if you did, then you made the choice and have to pay the consequences. Everyone is entitled to mistakes, so if she has only seen this other boyfriend for a short time perhaps it's to your advantage to call her up and be honest with her. Tell her you love her still. Perhaps she still cares for you. If you don't try you will always wonder. Good luck Happy New Year Marcy
