Wife blames my demands for kinky sex for her affair – I feel betrayed and don’t know if I can forgive her

DEAR DEIDRE: MY wife claims that my demands for kinky sex drove her to an affair.

Now she wants to make a go of our marriage, saying that we’re quits, but I feel betrayed.

I’m 41 and she’s 38. We’ve been married for 12 years and have a ten-year-old daughter.

A few years ago, I started getting heavily into exhibitionist porn — I’ve always fantasised about having sex while others watch, but I had never tried it.

I summoned up the courage to ask my wife if she would give some kinky play a go.
