You can run AND hide. From him - just not from us and YOU.
I spent a lot of time trying to figure out why my stbxAH was so hard to live with and why I always felt so alone with my pain. Was it because:
he was an only child and never learned how to get along in a family?
because he was spoiled by his mom?
because his dad was so hard on him?
because he is an introvert?
because he bipolar?
because he is anxious?
because he doesn't have any sisters and doesn't know how women think?
believe it or not, it only recently dawned on me that he is alcoholic.
but even that didn't matter.
The only thing that started to matter to me was this:
Who cares why?
My children and I don't deserve to live like this and I am not going to mistreated anymore. period.
It was a revelation.
Good for you for looking after yourself first.
