On and off boyfriend

hes no good for you. He sounds like an a$$ hole. You CAN stay seperate you just fall for his old ways. DON'T! If he treats you this badly hes not gonna get any better. End it whilst you still can AND DO remain seperate even if he begs you back stick to your guns say NO and remain strong. Move on and find a genuine guy who will treat you so much better and when you do, you'll realize this on/off boyfriend DID treat you like crap. Don't back down, stay strong, distance yourself from him, delete numbers, destroy pics, anything that reminds you of him. Hes had plenty of chances to make it right and he blew them all. If you've both cheated on each other then it sounds the relationship ended a long time ago. Dump him ASAP!
