Here is the deal, read the list, read what others have posted.
One of my biggest regrets when I got the "ILYBNILWY" line was I moved into our basement bedroom, I had my suspicions of her affair, but nothing was concrete. Looking back, I was way to placid. Instead, I should have forced her out of the master bedroom, tossed her stuff into the spare room and been done with it. Keep saying this to yourself like a mantra...
She is leaving you. She is breaking up your family. She is seeing someone else for god knows how long. She is self-destructing. She is the cause of all of this.
Why let her actions control yours? I am not an expert, but I KNOW if I wouldn't have left the master bedroom, things would have ended differently to some extent. I can say this though, if you DO go do this, make sure you are sober. I would consider getting a tape recorder or record the day on your phone. Wayward wives are all insane, especially in when there is an affair going on, you need to be protected. I would even consider bringing a 3rd party there, just to keep the peace and make SURE the kids do not listen to her bashing you (which will happen). Just take deep breaths, do not engage in anger, but lay down the terms. "This is our house. What you are doing is not ok. You can leave our house if you like, but I will not. etc." Good luck, it's 12:30 am here, I will try to stay awake if you need me. You got this.
