Just let it go. She doesn't like you in that way, or she did and finding out you were trans was a deal breaker for her. She said she wants you guys to go back to ignoring each other. That's a pretty clear "no" in my book. So do just that, ignore her, respect her wishes and don't attempt to contact her or get her to want to be with you or any of that. When a guy can't back off after a woman clearly says no, it's pretty pathetic.
