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.
