Should i expose the affair, or?

If you are asked about what is going on, don't lie. Just say it like it is. If your wife talks about keeping it secret let her know you will not lie about what she's doing. No need to instigate the "outing", take the high road. If she's ashamed to let others know that is her problem. You be the beacon of honesty and integrity. You have nothing to be ashamed of if you do that.

Otherwise, just keep up the GAL, follow the 37 rules, move yourself forward. If she wants to come along, she will.
