Hi there.

One of the first things I think about when something like this happens is "Is it really Love or is it infatuation, the excitement of something new or clandestine, or just sexual feelings?" All of these feelings can and are readily confused with Love. Could your pain possibly be a wounded ego (your masculine pride) from the rejection?
If I understood right, the class you are taking was a part of your job. Is there a possibility to drop the class for now and take it later on when your emotions are more under control?
At any rate, this woman has called a stop to what she calls "a game." The best thing to do is forget her, even though it will be difficult, and move on with your life.

These things can be just as painful as losing Love but only if you allow them to be.
My best to you.
