What do I do? I can't get over it.

That kind of chemistry is very difficult to resist, so I completely understand the attraction. I had something similar happen to me last year and it was electrifying and simultaneously idiotic. BUT, yes on the therapy and yes on avoiding him completely. Therapy, because deep down the attraction is probably about something else on top of the chemistry. Avoiding him, because the situation will only end up hurting you. When you get down to it, if you learn what makes this guy, and the situation so compelling, you can avoid people in the future who aren't good to you. No sex or emotional high is so good that it is worth suffering for.
