Hi K.,
I tell you what, I am going through the same thing with my ex. I do not have an order against him and we were never married but, I am going through the same thing. I am a 28 yr old with an 8yr old son. I have put up with his father trying to run my life for 5yrs, I am just finally putting my foot down with him. I got my lawyer and im figting him tooth and nail. Its going to be hard for you and your kids are gonna feel the anger you both have towards each other. My best suggestion to you is write in a journal. Write everything, about your mother-in-law and your soon to be ex. Jot everything that means something to you or your kids. Listen to what your kids say when they come home from thier grandparents house or thier fathers house. Dont make bad remarks about thier dad to them, let their father dig his own hole, im sure he is saying things or making remarks about you when he has the kids, let him this will show the court that he is uncapable of being a true father. Try and suggest to your lawyer that you want him to have supervised visits with the kids. There is a reason why you have an order against him and I am sure its because of what he has done to you physically or emotionally, but that in the judges ears and your lawyers because he treated you so badly who isnt to say he wont get revenge on your kids. I am here for you, you need anything let me know. Seems I am going through the same thing :) keep your head up it will get better trust me it does.
