Even though, H did a terrible thing, I do think he is indeed extremely remorseful and racked with horrible guilt, and that he will do everything in his power to gain his children's trust and respect again.
I am struck by what seems to be continued compassion and concern for your H and desire for him to rebuild his life and relationships with his children (whether with or without you) over time. Even in the midst of all that he has done.
You now have not only my sincerest sympathy, but my deep admiration as well.
Well, I'm not that compassionate. I admit I've called him and the ow a few choice words. None of which I can repeat here. I am cycling through rage right now and it's not pretty.
