Actions speak louder than words Zedsdead,a narcissist will say whatever it takes to get what he wants,but as you say he doesn't deliver the actions behind the words,he will say he loves you but his actions say he doesn't.It is abuse to say to someone expressing their genuine feelings of discontent that they are over sensitive and needy.

He has gone and you feel free your days are happy and enjoyable but he doesn't like that hence he calls you everyday proclaiming his love,if you go back to him he can turn round anytime he acts badly and say you don't know your own mind,it is a trap,he is trying it on cos he can he is trying to get you to change your mind and with that come the fact he will put all the blame at your door.

He won't take any responsibility for the split he will act worse than before and make you doubt yourself and your sanity bring you to the point of destroying you,your mind,sanity,safety and say it is all your own doing even though his words and actions are causing your confusion and you feel like you are going mad,then when you decide to dump him again he will come back with more proclamations of love.

On and on it will go this cycle of crazymaking behaviour for as long as you allow it.There is no other way it can go because THE NARCISSIST WILL NEVER TAKE RESPONSIBILITY.It always comes back to this this is the stumbling block,if he could acknowledge his faults and how he emotionally negates you and is emotionally unavailable and abusive,things could be changed but that WILL NEVER HAPPEN,cos narcissists see no ones feelings except their own,they are never to blame they won't except it,they may say they do to keep you but they don't mean it and they won't change their actions or behaviour and they won't stop the abuse.

If your partner has left do yourself and your family a favour and don't let him come back,it is for the best in the long term I promise.No good ever comes from an emotionally abusive partner, they never change either even if they promise they will they won't.Best of luck getting your head round things if he comes back it will be the start of another nightmare that gets harder and harder to get out of,do you really wants all that fear,guilt and confusion to start up again?All I can say is don't go there!
