Great point. Although I do know quite a bit about her and it was mutual preying.
I don't in any way think my husband or this other guy are not to "blame." Everyone involved was weak, selfish and opportunistic.
One thing I find disappointing is she was suppose to be working on her marriage. She had insisted (to me) she loved her husband, and was happy with her marriage. I think it's sad that when her husband became aware of everything, she didn't "wake up," and decide to seriously work on the marriage. I had really hoped she would try to work on things.... at least for her child...
By the way, I do have a few friends (3 women... 4 men I can think of off the top of my head) who would call themselves cheaters and are willing enter in relationships regardless of whether the other person is married or not. They'd laugh at your description of it being a weakness. (They also think my outlook is totally narrow minded and outdated).
Maybe they haven't "woke up"... maybe they never will, and instead will wonder when we will "wake up" to their reality.... perhaps they are completely happy with what they are doing in their lives. Everything is a matter of perspective.
There is no arriving, ever. It is all a continual becoming.
