I can't believe the crap you are doing and not feel guilty in doing so. When are you going to wake up? Spiritualy, committing Adultry is a Sin. PERIOD. Its against the 6th Commandment.
No one on this board is perfect, but how did you feel when your H did this to you? Pretty rotten huh. So now you are doing this to someone else. I suppose if someone were to jump off a bridge, and it was God forbid someone you knew, you would do the same thing. Two wrongs don't make a right.
People are given a free will by the Lord God Almighty to choose between Good and Evil, what is right and what is wrong. Get out of this picture sister.
I once read a story about a professional basketball player in the NBA say men can't help it when they cheat. Women approach these men while they are playing on the road at the bar, give clear signals what they want, even wait outside their hotel room. A man who does the will of God would not even consider to cheat on his wife. These women are nothing but sluts, but that doesn't mean these men should let them in.
What category do you think you fit into? Maybe you don't believe in Jesus or a higher power. But Jesus died for each one of us because He loves us so much. By intentionally commiting having this affair, where do you see you are right?
If I ever were to cross that line, my soul would be in danger of loosing it. Think about it at least and do the right thing.
