Ex H and I divorced three years ago. He had two affairs and refused to stop pretty much, so that was that. Our children 9 and 12 don’t know why we separated - they have lived through and I have reassured them as best I can. We coparent although strictly speak only about the children. I don’t know what is going on his life. I am settled. No new partner but happy. Ex has history of passing by my home and trying to speak to the children on random days of the week. Just an example of his behaviour. One thing that is really concerning me is the change in my DS 9. He used to love me so much - this isn’t me boasting - we were just really close. Now he’s rude, dismissive of me, says criticisms that are clearly not his thoughts. At drop off, he will look towards his father’s car if I go to hug him. I know some of this is partly growing up too. But I’m worried. He also can be quite dismissive of women already despite me trying to encourage him to be empathetic and understanding. What can I do to salvage this as he goes into the teen years?
