Ex h and I have 3 young DC.
We separated a few years ago (I left him). I'm in a relationship and have a new baby.
Ex and I don't get on.
He has DC 3 days a week, I have them 4. He's a great dad and kids adore him, he's always been very hands on and a big part of their lives.
He has a gf who lives up north. He drives 6 hours to see her every other weekend.
She's just announced she's pregnant....
He's decided to move up there and see them at weekends... Kids are devastated.
How do I handle this? Aibu to be pissed off and worried?
