Cynic,
I know its tough, but stay strong. You did the right thing. Whenever you have doubts that exposure was the right thing to do, just remember where silence got you. Repeated false "recoveries" while she continued to screw the OM. And know that 99.9% of all Waywards say some form of "I was going to work on the marriage until you exposed. I can't trust you and Im filing for divorce right away." They are just angry that their dirty little secret is out. Stay strong and follow the advice you get here. You may still lose your marriage, but you will be able to look yourself in the mirror knowing that you fought for it and didn't just go quietly into the night.

And please buy yourself a digital recorder and record your conversations with her. She may try to file a false police report that you hit her just to get you thrown either in jail or out of the house. Protect yourself and definitely talk to the police if she slaps you again.

Best of luck.
