Will my ex girlfriend come back?

So i dated a girl for 2 years. We decided to take a break to make sure we are really who we wanted. She started dating a new guy and said she is really having fun with him but still loves me. Well after 2 months of her dating this guy i kinda gave up on waiting (although i still feel like she is the one) and i moved on and started dating someone myself. Well when she found out she went absolutely nuts. Telling me she hates me, she cant believe what i am doing, have fun with my new skank, dont ever talk to her again ect. Well i feel like after that she really does hate me and is never going to come back, she will just move on to new guy. But a few of my friends are saying things like, oh man she is really going to want you back now after she realizes what she has done. So my question to you is....do you think after she reacted like that she is going to come back, or is she really that pissed and will never want to talk to me again?
