Infidelity Support Group
Any relationship in which one partner engages willfully in sexual relations with another outside of the partnership is considered to have experienced infidelity. This breach of trust is often traumatizing for the faithful partner as well as the relationship, and support is often needed to heal emotionally and to decide whether or not the relationship should continue after...

You had NO idea he was married.
Cheaters are very good at lieing! Ask any of us married to one!!! I lived with one having a 4 1/2 year affair with someone I thought was my best friend. And I didn't know!!!
How in the world were you suppose to know!
Be glad now-you know the truth. And be glad you are rid of that JERK!
He is not worth wasting your emotional energy on.
If you were the OW in my H's life. I would forgive you just as I have forgiven my H. Because you didn't know and he is a excellant liar.
Give yourself time to heal, get some counseling. And enjoy your life. Someday you'll be able to trust again.
You are obviously not a bad person, just human and believed the man you loved, which we all did here! We were all lied to.
Good luck and much peace to you.
Like srsnde said: You are the exception not the rule..
most women know.
So, I hope you can get the support you need. You shouldn't even be labeled as the OW. You stopped HIS affair when you found out. You did the right thing. This one is ALL on his head. Don't blame yourself. Learn from it and go on. And, not all men and lying, cheating, manipulating, selfish idiots. We definitely have our share of them. But, there are still good people out there. Maybe go into the next one a little wiser and check into it a bit more. But, don't write all of them off the list just because you found one worm in the apple.
