I am so sorry that she reached out to you again. She should not have.

If protection was your "issue," then why did she ask for it by sending you those texts and photos? She deliberately put you in a position where it was very likely that you would feel protective. Who wouldn't?

I agree that blocking her might be necessary but I totally understand that you don't want to right now.

The responses from your new therapist were wonderful and very appropriate. I am glad you found someone who can be helpful and not harmful.
