Dazed... first of all, take a deep breathe. I remember the first day after I found out about OM, horrible.
Second, know that your emotions are crazy right now. You need to slow down, I know you are in panic mode right now but panicing is not going to help you.
DO NOT give an ultimatum, you need to begin detaching immediately. Start focusing on yourself (easier said than done). There is nothing you can do to convince your wife that what she is doing is wrong. Affairs are very similiar to drug addiction, they both affect chemicals in the brain.
The best course of action is to start working on yourself, you are powerless over your wife. If she wants to see OM, she will find a way no matter how much it hurts you. The only person you can control is you, start there. You are a man, do not let this turn you back into a powerless child. YOU WILL surive this, you just have to weather the storm.
Also, make an appointment to see your doctor. Have him prescribe anti-depressants, they really work but take about 4 weeks to kick in.
We're here for you, hang in there and keep reading Divorce Remedy.
