in the early stages of healing and need your support and advice

I'm in the early stages of healing! I am just realizing this guy I've been seeing off and on for two and a half years is a narc. Well I looked at his facebook page a few minutes ago before reading further on this board that it's really a bad idea to do this (I can be so naive and lacking in common sense), so after reading it here that it's a bad idea to check his facebook page because what it does is be interested in his life and about him, when I should be focused on myself and my life and realize that I cannot give him sex anymore or be with him because every time I give him sex afterwards he gets so cold and then he doesn't even call me anymore when he says he will (he used to at least call when he said he would!)..... :( he always calls either days or weeks later to apologize saying "baby that's just the way I am, I told you I can be an asshole, I'm sorry baby I do love you"

Anyways he says he cannot add me to facebook because after the breakup I said some nasty things so he's afraid if he ever hurts me again (by not calling etc) that I would post something nasty on his facebook wall so that's why he cannot add me to facebook, yet he does love me and wants to be with me if we can move away from his family that he says does not approve of me.... anyways on his facebook today that I looked at he added a new female from his home town who is really unattractive and icky! (sorry for being so judgmental about it but for how much hell he's put me through I do compare any girl he interacts with compared to me and I think this is normal in dealing with a N for what they do to our minds and self esteem) anyways....

Can you all please explain to me what I need to understand about him so I can move on and heal and try to get a life :(
