Wow. Lots of advice here.
To get a little back on track....
-Detach yourself emotionally from the woman. (No longer your wife. Just a female trying to screw you)
-Hire the BEST attorney you can find.
-Forget about her feelings.
-File for divorce ASAP to put the ball in your court even if things turn around.
-DON'T get the kids involved if possible.
-Forget about what she wants.
-Don't have sex with said woman until court is settled.
-Most importantly, stay cool and run everything you do through your attorney.
This is all from hard earned lessons I have learned.
Good luck man.
