new assignment and happened to meet a co worker who was very nice to me.  We went out a couple of times (just as friends), but one night we were out drinking and he asked me if I can keep a secret.  Then he gave me a kiss (on the lips) and told me how he felt about me the past few weeks, and how working next to my office was very difficult.  It started from there.  Unfortunately, I'm practically married (engaged), and he's been married for over a decade (though his relationship is rocky).  I felt so guilty and I know it's very wrong, but I can't stop. We pretend like we don't know each other at work (many people at work have met his wife before), and it's driving me nuts.  But how can I expect him to act any differently, if I myself can't even live up to my current engagement commitment? Oh the situations we put ourselves into.... I would never have believed that I'd stray from my marriage. However after 3 years of virtual, husband initiated, celibacy I was feeling so down and unloved that I tentatively joined extra-marital dating site Illicit Encounters earlier this year (leaving hubbie and kids was not an option for me). Since then, I've met my wonderful and sensitive lover on the site (who was also trapped in an unhappy marriage) and our fortnightly illicit liaisons have restored my self worth and I'd venture to say have saved my marriage!
