They do not see anything wrong with their actions.
They can' t comprehend what we ( the lbs ) have been put through.

I feel the same way as you. I can' t be friend with my ex.
I do not trust him. I feel like he is setting me up for another bomb. Most time, he is.
There is RIGHT AND WRONG in my world / appropriate and inappropriate also.
I am not his life partner, nor his friend, nor his mother.
I am not friends with the kind of person he has become.

You should not stress over what she thinks.. Imo, she messed up the day she walked away from you.
