My ex (of 20 years) is similar to yours. I made this discovery: Did you ever wonder why there are women in church with “unsaved spouses” while there are very few men in church with “unsaved spouses”? I think it is because if the woman is a Christian, but the man is not, the woman will go to church and even take the kids, while he will stay at home and watch football, mow the lawn, etc.
However, if the man is saved but the woman is not, she will likely still go to church with him and the kids. I think there are a lot of non-saved people that go to church, but I suspect more of them are female than male. For women it is an effect of the gene that searches out security and being a part of something bigger than yourself. Men tend to value freedom more, and it is demonstrated in this when they are not believers but their wives are.
Then again, I may be over-thinking it. ;)
I don't know if she planned it that way, but I do know that she violated every oath she ever made to me or God. I see this with the women I work with as well. They are ruled by their feelings and make business decisions based on how they feel that moment.
I think women are essential for a complete life, and the positive attributes they add to this world is incalculable. I just won't ever believe one completely again. Even if they believe they are being honest at the time, their feelings will change and so will their truth. The can't help or avoid that.
