My girlfriend blocked me cause of rumors that she may have started. Should I reach out?

There is a rumor going around that my girlfriend slept with another guy that I know. I don't believe it cause there's evidence that she didn't. But to be sure, I told her, and she got mad cause I was asking. I even told her I am on her side cause I have evidence, but she blocked me, which had me thinking maybe she didn't cheat, but she is doing something sneaky like messaging other men? Should I reach out?
