So, This is the second time I have read this and tried to respond. The first time, I was so pissed off on your behalf, all I could think of was a large selection of colorful expletives.

I am so sorry you had to go through that in the first place. Whenever I hear about a sadistic sexual abuser, it always reminds me of the evil spawn I ran afoul of.

And now I am sorry that you are having him insert himself into your life now, totally against your wishes.

I am sorry your mother just doesn't get it.

If I could, I would protect you, and make sure nothing harmful got through to you.

Perhaps the staff at the hospital can require that your mother have her phone off when she is there with you so that she can't receive any messages from him while she is with you, and can't show them to you when she gets there.

Take care, and I hope you start healing and doing better.
