He is crawling back to me, and I really need strength right now.
I'm in the process of divorcing H, who left for another woman during my pregnancy and is a twat in many varied and glorious ways.
Except now, now he's being everything I wanted him to be when we were married. Devoted, supportive, attentive, helpful, generous... interdispersed with calling me every name under the sun because he's so "angry that we aren't together". He woud do ANYTHING to change the past, he just HATES himself, he's so SO sorry. 
Can a sensible person explain why this happens? He genuinely can't see that he is still a wanker. If he was that sorry he'd leave me alone. If it was genuine love then he wouldn't fuck with my head. I know I don't want him back, I just find myself weakening (in my head, never to him) when he starts with the happy ever after shite.
Kick me into touch, please?
