Sangromancer, you don't realize it now but you are far better off without this creepy person. It's amazing to me how many of these jerks there are out there, hurting people, then just walking away.

Furthermore, no matter how "gorgeous" his current squeeze is, I seriously doubt that will last long either.

Much compassion and many hugs to you. Just keep breathing and take it a few minutes at a time. Distract yourself if you can. And I'm sure the professional community will come up with some alternatives to help you through this, as well.
