That's a tough one but maybe he should have thought about all that beforehand. He has the right to pay child support and have court ordered drug treatment then visitation. If it's a safe situation.
No he should not be there during birth.

I think that as he is the father of your children then he does have a right to be there. Just because things ended between you and him doesn't mean the kids should miss out on their dad. I know It'll probably hurt you seeing him married again and having to face him but think of your kids first. I mean, its up to you you don't have to let him see them but having to explain that to your children when they're older is going to be a struggle. do what you think is right. The only way you could cope with it is to not think of him as your ex but as the father of your child and if it gets too much you could always ask him to leave and at least you would know that you did try.
