"I have not followed your sitch but have you contacted a lawyer? You need to find out your rights...praying for you and your kids"
Yes, this would be priority #1 if not already addressed.
"well after the big fight with her dad. detaching is going to be much easier. sad i cant even talk to my kids."
I will say this as clear as I can... Write down what is going on. Keep a log.. keep a journal. What you pay.. what is said by her.. so on and so on. Leave out the "Emotional" parts of it.. like..
9/25/09 W called wanted me to ship things too her. Advised her did not have money.
9/25/09 FIL (Father In Law) called told me not to call wife/kids. W blocked my number.
Keep it simple and to the point.. make sure it is dated at least.. times are even better if you have them.
Might not be a bad idea to look back and write down what you can remember.
Relax Eat Think Act normal React.. Smartly. Do something different. Emulate. Do Work.
