Long story short. Amicable split last year. We have children, I am resident parent. In 4 months he has had one of the children overnight on one occasion. All other contact with the kids he sees them at mine. This is his choice, I have made it clear he can see the children as much as he wants and have them stay at his as much as he wants.
He dropped in yesterday evening on his way home from work. Announced he hadn't taken his son's call the previous evening as he was at his girlfriend's and didn't want son to know.
AIBU to tell him that he's breaking government guidelines by going to his girlfriend's house, and that if this continues I don't want him in my house? Or am I being a bitter ex wife?
