You also have a Loooooong way ahead of you hehe. When it comes to relationships.. you live and you learn. Age has a little to do with it, but it also depends on the person and their past.

Anyway, I believe shes just as guilty as the married guy shes with. I myself would never date a married person because its not in my place to take the wife's husband away. Its terrible no matter who you are in the situation. Not to mention the kids he has with his wife. Thats the worste part! Those kids didnt ask for my slutty room mate to **** their daddy. Makes me so mad. Cheating is the one thing that really ticks me off.
