My wife’s revenge sex has ruined our marriage

DEAR DEIDRE: My wife had meaningless sex with a man she met on a girl’s night out because she wanted revenge.

She was convinced I’d cheated on her so she decided to get even. The worst part is, that I never strayed in the first place.

And now I know only too well, there is no such thing as meaningless sex!

She jumped to the wrong conclusion after I visited my ex to pick up some belongings. At the time she was convinced I had sex at the same time. No amount of talking seemed to reassure her.
