and I thought to myself that if she is really that insensitive then I not only no longer truly know her, I don't want to know her.
Wow, I have felt that way many times over the last year (or more!). The things xH says or does these days makes me so glad I am not 'attached' to him anymore, therefore don't feel the need to explain or justify his actions to anyone. And you said it perfectly, I don't recognize xH, nor do I want to waste my valuable time trying to understand him or get to know the 'new' person.
CONGRATULATIONS to S8!!!!!! And good job dad, teaching him the values of a Scout, and of an honorable, valued person. Keep it up!
