This seems like an absolutely terrible idea. He's a deadbeat dad who doesn't do much for the children, and instead of him making necessary changes to be more of a permanent stable fixture in their lives many years ago, he decided against it.
He also sounds controlling and abusive. It's his way or the highway.
It's his way only or the highway. He demands that you uproot you and the kids, and demands that you have to be together in order for him to be a father.
This isn't about the children for him.. This is about a "free" ride for him, and a new place. Control. He knows that you're not going anywhere, and that youll tolerate whatever he gives you..
He's not this "good" person that you make him out to be.
He's not interested in being a parent..or parening..He's never been.He doesn't do much now, he's not going to do much if you two got back together again. He's just using the children as an excuse to come back and get what he wants.
It is very likely that he'll up and leave again. He isn't use to being exposed to the kids..he isn't use to being exposed to you..He isn't use to being in a household with everyone. He is use to his peace and life mostly without being involved with children. He isn't use to the possible chaos. This may drive him away.
What will you do if he leaves? What will you do when he doesn't live up to your expectations???
No one it seems, is thinking of the children in this situation. Their overall well being, mental, physical, emotional health.
You don't even know what impact he will have on the children. He already has a negative impact. Coming and going out of their lives. Only seeing them when he feels like it..which isn't often. .refusing to get his life in order because he doesn't want 50/50..etc...
He is essentially a stranger. They have zero bond nor relationship with him. You want them to be accepting and tolerant of being uprooted, and a strange man who keeps abandoning them ..moving in...
All because you want a live in nanny and you're lonely.
You're willing to mess up their lives further..
And your own. You'd rather be tolerant of him and live in possible "unhappiness" until the children are grown.
Unfortunately you made the poor decision to have multiple children by him. One child was too many. Please don't have anymore children by him or anyone else.
How is this going to work out if you or him meet someone else?
You'd rather not contact organizations or social services for help?
Unfortunately, you're adamant about doing this. Not understanding the reason for this post.
