What does it mean when he holds my waist while hugging?

My friend group and I hug as a parting gesture, and one of my friends that I’ve had a crush on for a while now has recently held my waist really tight to him while hugging and patting my head. He got really touchy on a long trip, not that I was bothered by it… but I don’t want to be the first person to do anything, just in case I’m misunderstanding since he recently had an online girlfriend and then I ruin my friendship by bringing feelings into the mix. I’m terrified of ruining this because I DO like him…
