Be careful. Smile when you see him and do not tell him what you know or suspect.
As for the fireworks, apparently your xh isn't happy w/his new sandbox and playmate. If you don't want him over at your place, don't invite him. Discuss it w/your children and see what they want to do. I suspect that they don't him over either.
Enjoy the fireworks and ring that damn bell loud and clear to welcome in the new year.
P.S. Can you remove my name from the title of your thread? It's not fair to other posters to have me singled out to respond to others. Everyone gives such excellent advice here and it's better to not have my name appear in the titles. Many thanks and Happy New Year to you and your family.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
All I can add is "Hold steady". The man is clearly so unhappy and peed off with his new messy, grubby little sitch, the kid's reactions, that I think there is the likelihood he will get more and more desperate to hit out and to control. He will maybe do the hot and cold , nice n nasty, but you are too wise and he knows his options for being secretive are running out. Send all the evidence,accounts, notes etc of phone calls to your lawyer as I am sure you are doing. The other thing would be to have another trusty person there whenever he is there. A witness, if he is daft enuff to act out in front, but also mainly as a discouragement, preventative of him bullying you ,or being verbally aggressive or threatening.
But take heart.. his life is a vile and unhappy,unfulfilling one. The only kick he seems to pursue in an obsessional way ,is his attempts to control,hurt you, and get through to the kids. Just protect yourself, he cannot win,your life is your own,your kids love and admire and respect you,he is on a big loser here and he is desperate to make it his way.. But he cannot. The law is slow and an ass at times ,but if you have, and produce this evidence he is kindly supplying you with ,of his lying and failure to maintain,pay his share,meet his legal family responsibilities, then he will have to face that in the court.
Keep going my friend.. You are doing so well. Keep patience yet a wee while.. wait it out ,and fight your cause ,and be strong! A New Year and a new life for you all,is your goal! Thinking of you at this time.
