My 2 cents: Even if you decide to stay together and try to work it out you should still see a lawyer. Your going to be in a world of hurt if she suddenly decides that she is over the marriage and starts the process of taking you to the cleaners and possibly trying to gain full custody of your daughter. My good friend is going through a hell of a time. He's a good guy who worked long hours to make sure his wife and kids were taken care of. He found out earlier this year that she cheated on him. He stayed and tried to work it out. He thought that things were going well until he came home from work one day and the wife and kids were gone. During the two month period of "reconciliation" while he was at work she had been scheming hard be hind his back. She took all the titles to the vehicles, forged his name, and re-registered them in her name. She took all the money out of the joint accounts, and on top of that continued to see the guy she was side bonking. The icing on the cake was when my friend went to confront her at her mothers house they got into a verbal argument, she head-butted the door frame, called the cops, and had my friend arrested for domestic abuse. I got a frantic call last week from my friend, he had a verbal agreement form his wife that he could take the kids from Thursday to Monday. On Saturday night she called the police and told them that he "kidnapped" his kids. The cops came to his fathers house, took the kids, and took him down to the station. He told me as he was being loaded into the cop car in front of the house she drove by real slow smiling ear to ear the whole time Don't end up like my friend. Make sure you protect yourself and your daughter before you go back to your wife with open arms. Good luck in what ever route you choose.
