Recently 'officially' separated although our marriage has been dead for many years. Jointly applied for divorce a few months back. Currently very amicable, we are still living in the same house. We have 3 teenage children together.
STBXH jumped into online dating, hook up sites etc but settled down after a bit and is now on his second relationship since our separation.
I also have a new partner - long term friend that has developed into more.
STBXH's partner has a 4 year old child from a previous relationship. He was introduced to this child after 3 weeks of dating, which I was a bit surprised by, but that's none of my business. What IS my business, though, is that over the Christmas break, with the exception of Christmas Day, he has spent all day, every day with this woman and her child. Literally all day - from 8am ish to 11pm ish and a couple of overnighters (he is self employed and is taking a break over the festive period)
He is seemingly playing the doting Dad, when he never did the same when our children were that age. It hurts me that he seemingly cares so little for them at this point, although to be fair they have not made any comments other than Dad seems to be going out an awful lot these days. I am also very surprised that his partner does not find it odd that he doesn't want to be with his own children at all .
Is this just what some blokes do? As in abandon their children to impress a new love interest? Or is it just STBXH?
