It does get bad again and again and again. \It is because you love him and didn't want this to happen. I hope sykes doesn't mind me saying this but we were set back a million times and used to discuss why the hell we had fallen to peices again. I lost it only a couple of weeks ago and decided i was kidding myself that i was ok and yes i would have him back within a second. He was playing games with me though.
Only your husband can only answer why he is doing these things, i don't know, everyone is different. But i will tell you why my x was, he started to panic just incase he had made the wrong decision. Everytime i moved on he did something to check the door was still open. He sent me a romantic song, told me he still loved me, brought me FIVE dvd's. I would get all hopeful and tearful and seriously screwed up again. He couldn't bear me to be happy and move on. After so many times of being manipulated it gets quite tiresome. I called his bluff and said ok hon, leave her then. Did he buggery. I bet you a million he would come back if she left him though.
I would ask your husband to sort out his relationship before he gives you all these mixed feelings. You have been through enough.
And one more time you are not at all pathetic, not even a little, you have a broken heart, he did this, not you, remember that.
