I'm so confused?

I've been divorced from my ex HPD wife for over a year now. A few days ago I saw her Facebook. It was amazingly convincing that she was a Christian. I met her on a Christian dating site over 5 years ago. She quoted scriptures and seemed to truly love God. She was in Church everytime the doors were open. She also sang in the Choir at church.
While dating I noticed many inconsistancies in her life. She would state that she believed one thing then do the opposite depending on who she was around. I thought that she was just a baby Christian and that she was growing in her faith.
Anyway I married her. Later I found out that she cheated on her first husband and never told me about it. I found out from her brother that she was very promiscous in highschool. She had told me that she only had 1 boyfriend in highschool. I was willing to fogive these lies but, it all continued. She would constantly talk about other men at work, the playground while with the kids, even at a funeral she mentioned about some attractive men. She would talk about other men but showed little interest in our intimate lives. She would ignore me when around others. She eventually separted from me and began meeting with other guys and even brought them to her church. All the while saying that they were just friends. We eventually divorced.
What's confusing is that her Facebook is soooo convincing that she's a true Christian. I pray that maybe it's true and maybe she changed. I just can't understand why I couln't tolerate her in an intimate relationship but, she seems to be so liked by those in her church.
Any insight is welcome.

Well, but aren't they good at being "amazingly convincing" at anything? That's a sign right there.

My ex was very religious as well, although I'm not sure how that fit in with his PD. I haven't read much linking the two, does anyone else have any thoughts or observations?

I know 2 NPD guys who have their churches really fooled.

But they can't fool the guys who have worked with them for 30 years.

We have to wear "hard hats".the place is like a chemical refinery more or less.

One day someone put a stcicker on one of these NPD's hats while he was off.

The sticker said."Jesus loves me, but everone else thinks I'm an ass_____-!

My ex was an HPD, I have to work with her every day. The cook there is currently having an extramarital affair with her. He is a priest. Its hard, sometimes no matter how much you know about psychology it does little to stifle the kind of resentment one feels after seeing that. I find myself hating her and every other HPD, I hope you are able to completely detach yourself from her. Some of us were not so lucky.
