Well, in the end I wrote back to her and told her my actions and the ins and outs of my circumstances were none of her business. And that if she had concerns about my husband's mental health could she please act as she sees fit instead of passing the info on to me. I reiterated that any of them can take him to the hospital if they are that concerned. I can't do that as I am far away with a baby.
She wrote back to me that she hopes I find happiness and peace with my choices. lol. Passive aggressive much. I told her to look after herself and not worry about me because I will be fine.
I don't think I'll hear from her again.
