Call it off. I'm sorry to say this. Don't let yourself be treated like this. My best friend went through this back in December (they were engaged too). She told him she hoped he died and she hated him. He tried to fix it. She gave him the same crap. I helped him out and he decided to start "fresh". He stopped trying to contact her and all that stuff. She started trying to call him again. She wants him back and all that crap. Just to think, the same person that called off the wedding and told him she hated him now wants him back. Now he's making 6 figures and has 3 brand new cars. Move on. It'll hurt, but you'll get through.
