My Cheating Husband Just Inherited $3 Million , Should I Still Divorce Him?

One married woman is torn between a rock and a hard place and wants people who chance on her dilemma to help her make a decision she would not regret .
In a post that reads :
“My husband recently inherited a big sum of money when his father passed away. His father left 75% of his estate to my husband, which is worth around $3 million.
My husband has been having an affair for some time now and I will confront him about it soon and, after that, I intend to divorce him.
What rights do I have to his inheritance? We have five children together and I went through a lot with him for many years and I want to punish him for going behind my back and having an affair.
I know I’m a bitter and scorned wife, but what are my rights with his inheritance “?
Any advise to this scorned lady?
