DEAR ABBY: My husband and I have been into swinging for 20 years. Everything has always been “no strings attached.” I was with one man several times before he married his current wife. She’s very religious, not into swinging and doesn’t know he is. I’m so attracted to “Nick” that I dream about him and have met him outside our marriages. I know it’s wrong, but I can’t keep him out of my mind. My husband doesn’t know, and I know it would hurt him deeply. Should I tell Nick, or quit writing him on our swinging site?
