Thea, I’ve read your responses. I have a few concerns. It’s perfectly natural to have a crush on someone. Crushes are fun and basically harmless diversions from everyday life. But you have twice described your attraction to be painful, which I find a little odd. I mean, if this crush isn’t “fun” anymore, if it’s actually causing you emotional pain (a sexual death), then I would heartily recommend you either exit the scene entirely or quit indulging your fantasies about him. Because they are now doing you more harm than good.
You have not mentioned any other romantic interest. I hope that you don’t spend your time obsessing with particle to the exclusion of “lesser” men. Because you do realize that particle may seem ideal to you, but that it is an illusion. He is a human being. He is flawed. He may even fart.
And remember, your ideal partner is, first and foremost, someone attainable.
Finally, he left the first company and now you are both coincidentally working for the same company again. I certainly hope that you didn’t interview with the company he went to work for any reason non job-related. Because if the fact that he went to work there had ANYthing to do with you being there, then you have crossed the line. (And if you were a male pursuing a female, it would even be frightening.)
Sorry if I’ve over-reacted, but the mother hen in me is telling you that it is time to quit fantasizing on particle and focus your energy on finding somebody else, somebody attainable.
