XWH told me his OW was also a BW at one time. I suspect this was a lie to garner "sympathy" for OW.
I found this to be true with the OW in our situation. She 'said' she was betrayed by her XH when he was on his deployment and she was STAHM. Hmmmm so then if that is true why would she do the same thing while I was on my deployment, while my FWH was the stay at home spouse??? One would think that another knowing what that pain was like, wouldn't create pain for another. Oh the lack of empathy!
What we found out to be the truth....OW lied. Gee big surprise! OW did the betrayal on her deployed XH but painted a MUCH different picture. So as for believing them to be formerly betrayed themselves? I believe either they have zero empathy or are seriously damaged. But its my 2 pennies worth.
