Is my wife having an affair? Married 15 years, two children 6 and 10. She isn't affectionate and sex is monthy if at all. Lately she has a sex hang-up, avoiding it all together. My suppitions led me to check her E-mail. All of her recent "sent and deleted" activity are gone. Her log on her sell phone also deleted. I've discussed the sex issue with her and she says she has no interest.
