Should i expose the affair, or?

[Complex]

Also think about that if you ever reconcile with your W it will be much harder if, especially on your side of family and friends, the picture everyone has of her is completely destroyed through exposure. It will make the step towards reconciliation and the reconciliation itself much more uncomfortable for your W, which is absolutely not beneficial for you and your M.
Always know what you really WANT, then weigh if the actions you are taking are BENEFICIAL or counterproductive!
Makes sense?

In my opinion it makes sense to always talk about your W very respectful. You don't have to agree on what she's doing, but you can still love her for who she is and think in high terms of her. It's counterproductive to make her look very bad. Think about it from the psychological side, how would you feel?
