Thanks so much for the reminders. It helps to try to keep it in perspective. That these behaviors that are just to uncharacteristic of the man I have known for almost 20 years are due to intense pain and confusion. I talked to my one friend outside of the boards who knows a lot about the situation this morning and she reminded me that with all the pain he is going through right now, he really doesn't need me to "abandon" him as well - some days I feel like throwing in the towel. That day may come down the road, but for me it shouldn't be yet.
I think with most things we as sane human beings feel that understanding helps us to cope but in this case there is no understanding of what is going through their heads- coping has to be reached other ways.
Sigh. Yes it is unfair. But then so many things about life are . . . we just need to learn to deal with it.
