I couldnt, no wouldnt, have have put this man before my children, id have got rid of him years ago!- so i have no words for 'kind' advice- you know you should have done that back then, youve 'allowed' him to bully & belittle you& your kids for years and hes still getting away with it! 'He just wont go'? I would have packed his bags years ago- ive no idea why your kids would want to stay for days at a time there they must be gluttons for punishment as well.sorry but ive no kind words for anyone who would put a bloke before their own kids, especially one like him, under the guise of 'loving him then'- its tantamount to helping him be cruel to them.if you had no kids then it would be you alone who was daft enough to stay with him but with your children, putting them through that life?just no.- water under the bridge? I doubt your AC feel like that about it, you're very lucky they still come see you, let alone bring their children.Get the legal advice,first split the money, then make him leave, if he turns nasty ring the police on him.If i were you i would then sell my own house and move to a little place nearer my AC. You could try start making it up to them then over allowing this nasty bloke to control all your lives for so long.Sorry if you feel my plain speaking is harsh, but i feel it has to be said.
