. . . But I thought everyone on here says not to bring up OM, but whatever you did obviously had an impact. . . .
Even though my WAW moved out a few months ago I want ask her if she's still seeing OM, (which she denied when we were living together)
. . .
You will notice that Zew didn't "ask" anything. His was a firm "I know all about you and ________, and it has to stop" type of stance.
What people around here recommend you avoid is constantly asking, begging, accusing, supplicating behavior. There is NOTHING wrong with a strong, decisive, "I will not live in an open marriage and I know all about your affair" stance . . . in fact, I strongly recommend it.
