Do you think our friendship is leading to affair?

Didn't you ask this before. You are definatly playing with fire and you are gonna get burned. You are going to destroy a marriage and break up a home and for what? A man that is cheating on his wife, wants to use you for his own diversive pleasures, is going to wreck your life and cause you to punch that one way ticket to hell? You need to stop this immediately and send that man back home to his wife. He is a cheating lying creep and you will get exactly what you so richly deserve if you continue to play with fire.
