No matter what. No matter that she tells you you did nothing wrong. No matter that she tells you she wants it to be amicable. No matter that she tells you she still loves you. No matter that she tells you she's sorry. No matter that she tells you she doesn't care about the money. She doesn't love the other guy. She wants joint custody of the kids. She is very, very sorry. She blah, blah, blah. No matter what. GET A LAWYER. From the get go. Don't fuck around. Pay them. Follow their instructions. She is no longer your wife, she is your enemy.
