From a lawyerly perspective: in the case where the harm is obvious as is the connection between what the therapist did and the harm, you don't need to spell this out. Like the example from the other poster where the therapist's behavior led to the ER. But that's not your situation.

It is up to the board to make the conclusion that she violated ethics and up to you to explain what happened and how it affected you. I don't think, on their face, that hearts and nice email messages, communicate what's wrong. It's clear she's not hitting on you and you're not claiming that. So I think you have to connect the dots between those things she said and did (and I'd avoid using labels like boundary violations) with the harmful outcome(s).
