I don't know NLW I am thinking along the lines of BM as well. Own the situation and go say hello - let the kids feel they are able to approach their dad? I honestly don't know. It's super hard on you but he is THEIR dad first and foremost. He doesn't belong to OW he belongs to them.

Sending you peace and strength.

And lots of love
