Agree with the get an attorney. Don't hesitate to ask how much it is going to cost you......no ask, big bill.....
Another thing worth considering, and it may not be a problem at all, but thought I would just throw it out there.......you may want to stay away from other women until it's all over. Pissing off the ex will likely not work favorably. My 2

Good Luck....you'll need it.
