Son, you need some anger management. If you love her, then you've got to give her some space. She did the right thing by breaking up with you. You have NO right to tell her who she can and can't hang out with, that is NOT your decision. So, you can fix things and have her back, or keep behaving like a 2 year old and have a series of failed relationships for the rest of your life. Get over it, you're the ONLY one who can control YOUR behavior.
