I am going full no contact I won’t be allowing him into my home. I’m not stopping him seeing our children but I won’t be making any arrangements for him.
I’m sorry it has come to this but I think you really don’t have any other options at this point.
It is at the point where YOU have to stop enabling him and his lies and allowing him to keep you as his plan B (back up plan).
The audacity that he thinks he can live within your home and cheat in you — in front of your kids. 
Every interaction with him turns into an argument. I’d like to suggest that there is a way out of that loop or warp. Here are a few suggestions:
No contact or contact only via text (which I may have suggested earlier)
You don’t need to respond to ANY text message that is rude or insulting or offensive etc. By ignoring him you are removing yourself from his manipulative control.
It may be hard at first to ignore him, but gets easier over time.
When he comes to pick up kids, try not to have to see him. Have a friend or relative available for hand off until he can prove he can stop being argumentative and manipulative.
Set a deadline for starting at least child support. Do not let him keep you in limbo longer than necessary.
Here in the US the person that files for support first gets the largest share. If the OW has a child by him and files first, she may get the larger share. Just something to be aware of.
Stay here for support. You have made a hard decision but I believe it’s the right one for where you are right now.
Just remember — he’s no longer the guy you married. He’s morphed into someone or something else.
