I can't forget my husband's betrayal What am I supposed to tell him?

This kind of thing should be said in person, say it. Aren't you going to tell the world? You embarrass him and only alienate you more and more. Don't do this. You should calm down and talk about it, or you can just tell him what you think and see what he says. If he really loves you, he will talk it over with you, but he probably doesn't know what to say to convince you again.

But in any case, this kind of thing should not be made public through discussion, which is not conducive to your marriage. He goes to extremes easily. Don't.
