Don't forget also by being actively invovled with a married person you could be potentially helping hurt the other partner very deeply. That isn't the kind of mark I would want on my record when I get called to account. It is simply demeaning to your own character to be knowingly invovled in an affair. lacking better words just tell that bitch to keep walking.
