it's quite human to be jealous Lexicus, that's mean you truly have a feeling toward your love interest, I guess both man or woman will be equally disappointed to their buddy if they somehow taking their crush over.
Just a while ago, between two female employee in my office get a problem toward each other, because her best friend that she bring to accompany her meeting her crush (he is a worker of our company vendor), ending up dating her very crush. This thing are something that we feel all gender. Don't you agree?
