...or an e-mail to your account...from
[email protected]....(which of course is sent from yourself)...and leave your outlook open so she may 'discover' the e-mail...
There she (you) can explain the she really don't want to have anything to do with you anymore, but that she misses the dominant sexual role she had over you, telliing some storries abot how she used strap-on on you, how you two had threesomes with this other guys whom you willingly sucked often....and so on...should be humiliating enough for you I guess....

And then she (you) ask if your current gf is treating you the same way, or if she is just another vanilla cunt...
