Ex wife has a new partner, we broke up 9 months ago, my decision. She told me tonight that she has met someone. I told her that we will need to set some ground rules regarding the kids and her new partner. She said it is none of my business and the kids won’t be introduced to him for a long time. Called me a hypocrite as I introduced the kids to my girlfriend 6 months ago despite she asked me to wait. I just want the best for my kids and I know they won’t like the new partner especially my oldest. He is too attached to his mother and did not like my girlfriend when introduced to her and he still doesn’t like her but I fear if his mother introduce a new partner he will be devastated. What should I do?
