So I know Everyone is going to judge...?

Well....I know already everyone is already going to hate....but anyway, I did cheat on my husband, we were having hard times, I already know I made a mistake, and I slept with someone else. I have told him of the wrong doings I have done, and luckily he had decided to forgive me (thank goodness, and I know I don't deserve it) Anyway, my question is, should I let the wife of the husband I slept with know, or should I let them be?
