Ok I had to look up your previous posts, I remember you now. I confused you with someone thinking you have grown children.

If your kids are minor you’ll need to figure custody. You’ll either have to pay child support (and it’s separate from alimony) or you’ll have kids full time and she’ll have to pay you (she wouldn’t want that so she’ll fight for custody l). So your situation is more complicated.

You mentioned that she doesn’t take care of kids or house so she can’t claim to be stay at home mom or housewife. You need to start documenting things diligently including her not doing any child care. Keep a journal with details times of the day and dates etc
