Despite having one or two jealous bfs one of which tracked me down after only 1 or 2 dates to an obscure location on campus I was found to be working alone on my project. One was simply unusually upset not to find me where he expected to find me while visiting me at work. I later found out both of these compulsively jealous bfs were in fact cheating on me. Another friend commented to me that knowing one's own nature more often determines jealousy than any actual reason to be jealous. That was one of the most accurate pieces of information that I have ever been given!
