Parents mainly fathers but everyone answer please? Why do I get jealous?

Awww don't worry its not your fault. Its like your an orphan and your seeing families laughing and having fun while your all alone in the brutal world. You can't help but feel jealous toward them and cry a little:) he probably doesn't say anything to you because he might feel like he'll mess up again or hurt your feelings. Sometimes it's good to leave people alone for a while......it's what a human does!
