Open marriage?

So I have never been the type to be with just one person until I met my husband but I find myself missing my old self and wanting an open marriage we agreed once to try it and I found someone and started seeing him my husband however didn’t find anyone so it was just me seeing someone else but it ended up not working out cause both my husband and the guy I was seeing got way to jealous and I asked me to chose which one I wanted to be with so obviously I chose my husband... the thing is for some reason I feel the need to have more than one partner but my husband is definitely not open to trying it again not really sure why I’m making this post maybe looking for advice on how to handle my desires?
