One sided FWB advice

So I just started college and I’m in a friends with benefits relationship . This is a new experience for me, we pretty much act like a couple even in public sometimes. It got kinda messy because I ended up catching feelings and got jealous when he called someone else attractive. We are still FWB but it dosent feel the same I feel like he dosent want to hang as often or I’m just too clingy . I literally slept with someone else while being FWB but I would throw a fit if he did it . How can I stop acting like this or stop being so clingy on to him ? 🤦🏼‍♀️

It’s just that I like him so much he’s so nice and everything it’d want in a boyfriend but he simply dosent want to commit In this point of his life.
