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

It is normal to be attracted to someone else... It is just infatuation. Dun risk your marriage, since you are happily married. I have seen women regret their actions and their life is wrecked. The other party knows you are married, and still want a fling with you, cos he is not going to have any responsibility towards you, this is not real love.
