Has to be one of the most painful things I have ever experienced. No matter how hurt I have been by my XH, seeing my baby crying so hard because he wants his daddy home and just can't understand makes me ache. It makes me want to hurt his father so he can feel just the tiniest bit of the pain he has caused.
I have explained that we are both happier now, but that doesn't mean anything to a small boy who just wants his daddy home again. We are 18 months down the line, but it still hurts him so much. Not helped I suspect by me having a new partner, and by XH finally being open about his relationship.
He asks why, and I can't give him a decent answer. I just hold him as he sobs himself to sleep. I remember the pain from my own childhood. I just want to take it away and make him not hurt like that. 5 is too young to feel like that.
