Hi Chocolatemilk.
You've been together 6 years and have been fighting the entire time? He's been abusive most of this time?
You left to get away from him, and tried to move on with your life and now he's giving you a hard time?
a) don't ever speak to your so called friend again....what an awful thing she did to you.
b) get rid of the guy - he is nothing but bad news - you didn't mention one thing you liked about him, why you love him, just all the things he said he was going to do but didn't and how he is continuing to make you feel bad.
I don't see this guy offering you any second chances when you've given him plenty - give him the door.
