Fooling around behind wife’s back

For the last six months I have been fucking around with my coworker. No full on sex, but lots of sexting and kissing in the stockroom. We came close to fucking one time and she told me no because she didn’t want to if we weren’t dating. The worst part is my coworker doesn’t know I’m married and my wife doesn’t know that I’m cheating on her almost nightly with someone much younger and sexier than her.
