Yeah, that sounds like a real good supposition on your part. I suspect that's exactly what he plans to do. And, if his next sugar mama tosses him out, he'll need your house as his hotel.

So your daughter had "a breakdown," whatever that means. Well, maybe you better just accept that he is in control. You can decide to just let him come and go as he pleases and do whatever he wants. Maybe that will reduce tensions. If you do that, make up your mind to stop exposing your kids to you hating on him and fighting with him. Just meekly accept that you got yourself in a jam that there is no way for you to get out of. That's pretty much the thrust of everything you post.

Everyone contributing pretty much affirms that this is a bad situation you're in, and everybody is supportive of you getting him out. You've gotten plenty of good advice. Now, if you really don't think you want to throw this guy out and that you can't, even if you want to, then just keep on as you are. I don't know what else anyone can tell you.

If you basically want to vent about how awful he is, you can do that too.
