I have been married and had someone hit on me recently, he was pretty good looking
Oh, you go girl! What did you do?
It was flattering of course, but I love my husband and would not ruin our relationship for a few moments of pleasure
Awww, what a sweet woman you are. There aren't too many like you out there anymore. 
You have to think about your family, your kids, all of those you would hurt, for what?
