I am really, rather terribly attracted to a guy from work.. he too does give subtle hints... I am a mother of a 4 year old with an amazing sex life with my husband but my mind still wanders.. And I can't control it... Any reason why this is happening-I must add here that I am very happy with my married life yet feel like straying-Pls advise

If I were you, I will try to avoid the temptation and stay away from the guy, be it quitting my job or change department. I will not want to destroy my own marriage life because of unable to control my own temptation. Try to appreciate of what you already have with you now and don't make mistake and destroy a family. I have a friend who can't resist the temptation and ended up with a divorce and separated from her kids. She is very regret now but nothing can be done since the mistake has already made.
