I just got this random spurt of jealousy! I never usually get this way and the worst thing about it is the fact that it is an old crush. I use to like her a very lot, but that was months ago now and I have since then focused elsewhere. But, I just had the adversity to witness my old crush getting into a car with another dude after doing a quick glimpse through my window. I stopped focusing on my book at that second! I know this is rather silly, and I can't understand I why I felt this way, but I suddenly got rather obsessed and those physical feelings of jealousy came in. I picked her up, like I said, a very long time ago but I don't understand why I should even get jealous like this. This situation could also be totally distinctive to what I am concluding, but I just can't understand why I got so jealous. Any ideas?
