Being a mistress

Yes! This isn't only effecting you and your "mister", especially if he has children. Try not to just think about yourself, put yourself in this woman's shoes. It doesn't matter if she's a horrible person or whatever, the point is if she finds out it will hurt her even if she pretends it doesn't. And if this guy has kids it will hurt there WHOLE family. Is that really something you want on your shoulders? Is a guy really worth that?

Plus ask yourself why would you even want to be in a relationship with someone who is married and committed to someone else? If your thinking you can steal him away, chances are that won't happen, and even if it does who's to say he won't cheat on YOU down the road? It sounds like you have some commitment and maybe even some self-esteem issues to work on if you get a kick out of running around with someone else's husband.
