Why did I feel jealous?

I don’t love or want my ex *Michael;* nor am I very competitive. When I heard through my ex boyfriend’s family that he’d gotten married and saw Facebook pictures of them looking so happy on their wedding day, I felt a combination of happiness for them and some strong jealousy twinges. Did his wedding remind me of the fact that I have yet to be married? What am I jealous about?
