I'm sorry you're dealing with this. It's not your fault--the blame rests entirely on your therapist. It's their job to hold the boundaries and behave in an ethical manner. There have been others on this board who have dealt with similar issues, so they can give you more advice.

Have you told your current T about it?

Also, I wouldn't publish his name, because this is a public forum, so he could theoretically try to sue you for libel.
