Am I right ?

I am married, kids and all that stuff . Suddenly a year ago a beautiful women came in to my life .. ohhh my she was married having kids and by the way she was just as beautiful as Shakira , I don't know what she saw in me but she fell for me .. started messaging me even she said we both are married and we could have a secret relationship.... The exact thing I wanted or I have been posting on SW..... But there was a guilt in me and i refused her offer . I don't know why I did that but I thought it was against the moral laws at that time. Now some times I regret I think there should be someone whom you can talk to or a frustration that must be expelled.. I don't know I am thinking straight or not ...
