Well, if you're still having sex with it's no bloody wonder you can't get over him. Where's your self-respect, doll? Surely you know that is the only reason he's still around... simply because the chances are high that you'll do him once he graces you with his presence once every other month or so. You deserve better than settling for only what he gives you. Stop sabotaging your own emotional health and get on with your life without him in it. You're a booty call and he just says things that he knows you'll want to hear in order to make you think you're more to him than that. If he had genuine I-want-to-be-your-boyfriend feelings for you, if he valued you in that regard, then this thread wouldn't exist and you'd not be crying that you even have to get over him, never mind that you can't.
Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.
