Thank you everyone for your advice. I am never alone with him, my hubby is always with us, since it is his friend. I would never act on any of my feelings. I am very happily married and would do nothing to risk losing what I have. Recently when we have the chance to hang out with this guy, I have said to hubby, I just want to stay home tonight. But I guess I do agree that it is natural to find others attractive, we are human after all. I am sure my hubby has thought another woman was attractive before. Anyways thank you again!
