Wild - I am in a similar sitch..my wife for all intensive purposes of done. I have three kids so I understand your concern. Look buddy your scared right now (so am I) but do not react based on your fear. Remember you cannot control what she does but you can control how you respond. In terms of the kids, you may want to do some research on the laws in your state as it relates to custody. In terms of confronting about the OM - thier are two thoughts...some will say confront other will say do not confront. If you decided to confront do you feel in your heart of hearts that you are ready for outcome of the confrontation. If not, then I would not confront. How old is your W? How old R the kids? Each sitch is a little different. You may want to talk to a DB coach to see what they think.
