Jealousy

I need some advice. My boyfriend is way more social than I am. We both have our friends, but he tends to hang out with his more. I often find myself getting jealous. I wonder if it is because I feel like I’m missing out on something. My jealousy and feeling of missing out does effect our relationship and I don’t know how to work on this before it becomes too late. Part of it could also be me worrying that he will think I’m a loser for not hanging out with friends as often as he does.
