How can he treat you well when he calls you fat and checks out other girls? Do you call this respect for you? If you're serious about being with a man who will respect you and put you on a pedestal, so he doesn't have to be changed, then you'll dump your BF sooner rather than later. You need a man who generates positives all the time. Why wait to after the September holiday when, going by your post, you're ready to move on now? After all, you've already recognised that you're better off as friends. Ask yourself, based on his attitude, if he'll even be a friend for you afterwards. And if your BF can't respect your decision about your relationship with him, then you need to do what's good for YOU and that's move on.
