I would talk to your new T and see what she says. It may come down to a he said, she said. I would stick to your guns and keep saying what he did exactly and if you can remember the dates, then even better. If you wrote about it, then bring it to court. Also, ask if you talked about it with your T, then ask her to come to testify. It's not going to be easy. Being sexually assaulted is wrong and going to be hard to prove. Sounds like your old T is trying to save himself.
Good luck
