What would you do if you found out that your spouse was cheating, And your parents knew, but concealed that fact from you?

Say you're a son or daughter of parents (we all are), And say your spouse cheated on you. Not only did they cheat, The the in-laws and your parents knew But they chose not to tell you because "I dont want to interfere"

I promise you this, if i was in that situation, i would cut all contact with my parents and never speak to them again.

Question inspired by some of the idiot comments on this question

If you found out that your son or daughter was cheating on their spouse, would you say anything?
