That being said - and to get a bit more general and not make this a Christine-only Thread:
The situation has reminded me about different concepts and variants of shame:
If shame leads to positive social connection, (re-)integration, contemplation what one wants, support, and/or is part of needed inner cleansing, it can actually be helpful. Some researcher call that pro-social shame.
Besides, let's face it: A failed marriage - at least in many societies I know - has also a lot of potential for shame of various kinds. Decide for yourself how you think about it.
Anyway, if an unpleasant situation, a personal failure etc leads to alienation, pillory, humiliation, etc. then shame becomes anti-social, destructive. Even more so when interwoven with double-standards. (Like some family members preaching chastity for singles, but violating their own standards, while the one family member of all, that actually wears a belt (w/ supervised breaks, full-time), is hold up to ridicule.)
