Let her look all she wants. Simple as that.
Block her # if she continues to send hate your way. She'll get over it.
It's more than likely, since she showed no character by attempting to encourage you to be unfaithful, then chances are highly likely that she has an enlarged ego, as well, therefore cannot deal with rejection well...or at all.
So long as you don't play into her head games, all's good.
I have to wonder......Where is your girlfriend throughout all of this?
Just curious.
You're doing both yourself and girlfriend a good thing by placing the chickadee where she belongs...OUT of your life.
Grats..
