You don't need to be embarrassed. This is so very very human.
That sounds like a nightmare of a situation. I've had some experience with betrayal and multiple "disclosures" for lack of a much-needed better word, and I can only imagine the trauma you're dealing with.
I'm so glad that you've gotten yourself out of a bad situation, but I'm so sorry you were in it in the first place. Sending you a lot of love. Thank you for sharing with all of us.
