I hope you're doing better, after your rough weekend.
I remembered that if you wanted to look at a really detailed thread about the various manifestations of MLC, a poster called Trusting had one up a few months ago which was really useful. I'm not so good at linking things (H is the computer whiz in our house, and I'm not asking him!), and I hear that a lot of the older threads are hard to find now, but it's an idea.
I was also thinking about how most of the MLCers are caught up in mommy-issues. Some do become their fathers for a while, and it certainly seems as though your H followed his father's suit by experimenting with what he knew were inappropriate sexual urges. You mentioned that his mother knew about his abuse yet ignored it. As a mother, apart from that, what was she like? What did she teach him about women, and his own self-worth in comparison to her?
Here's hoping you and the cats are well, and that better weather and better times are not far away....
