My wife and I separated. She slept with another SM who claimed he was single, turns out he lied, and now the spouse has found out. I was just wondering what the worst-case scenario looks like. She told me everything when we decided to try and work it out.

Update: We were separated with the intent to get a divorce. We both decided that we wanted to work it out. We had been fighting due to family stuff for a while. We agreed to cut off family and work it out after about 6 months of separation.
