What he want? anyone have similar experience?

I am happy that you and your children manage to survive that very bad relationship you were in... And if I were you I would get a protection order that will prevent him for coming within 100 feet of you and if he makes any effort to contact you via e-mail or by any other means then you can have him arrested... And if it really becomes necessary you can also have the police watch his every actions..... So call your local police and let them tell you how to obtain a protection order in your area.........
