He sounds like an incredibly selfish jerk. He takes the car every Wednesday when he knows she has to pick two kids up that evening. Really?
But, I can understand her need to have him figure himself out. I'm sort of dealing with that right now. My husband just keeps insisting I am his world and that he's not really gay. I feel like I need him to figure it out so I can say, "see, I'm not abandoning you, I'm giving you what you need" Why I need that I don't know but I do. He made an appointment with a marriage counselor for next week. He thinks it will save our marriage. I think it will prove what I know to be true, our marriage is over.
The difference between myself and the author is that when I say he can go screw whoever he wants, it's because for me, our marriage is over and I really don't care anymore about fidelity. That kind of love is long gone. Now it's just all logistics of how to end it and not destroy our children in the process. I won't be having happy, family moments with him and I certainly won't be having sex with him.
I feel very sad for her...she did all she could to save her family and made horrific sacrifices and it still didn't work.
