It sounds like you are going right back to the way it was pre-tryst, as if it never happened. You saw where that got you.
Sorry I sound like a broken record, but it WILL take 2 of you to get this ship righted. Don't just give up and settle, keep trying, especially with your counselor. But it also sounds like you have never told him it was a paid escort not someone you just hooked up with. Hopefully, honesty will breed honesty.
