He hasn't moved on. He wants to be with me and the kids AND drink.
he wants to be in the house with all the accouterments, which happens to include a wife/women person and small humans. it also means a stable roof over his head, food on the table, clean clothes, clean bed sheets, clean towels, magic toothpaste that never runs out, and if there IS a God.........cold beer in the fridge. he's mentally a five year old that doesn't wanna go to school, or do his chores, or have to go to bed at 8pm.
obviously option B with the new woman person isn't quite meeting up to his scrupulous standards and meeting the threshold of what he is entitled to.
continue to do whatever you have to for the children's safety and security. he always has the option to hire an attorney and make claims to the court if it matters THAT MUCH to him.
