Since you have already taken the first and only step, which is
to email her, and she doesn't reply...
There's only 1 other thing you can do.
Ignore her.
Lets look at it from a practical point of view. What Can you do?
You keep protesting your innocence, but there's no point, since its
already out of hand.
She doesn't reply you, although you spend so much time emailling
her.
Just forget it and ignore her.(Oops, that's 2 things.)
Get on with your life, there are much more better things your time
could be spent on, then worrying on something that you can do
Nothing about.
From another point of view...
Maybe you can seek her out in real life and have a talk. But things
could get ugly, so you best get a few friends with you,(provided
you 2 eventually meet.) But then again, she may choose to do
nothing also.
So why bother? Ignore and forget is the best~
