Unsure

Me and my ex ran into each other at the club. He waved and I kinda approached him asking how he was. He got us drinks and we talked until closing. He offered to drive me home so fast forward we hook up at his house and the next day we spend the entire day together. We shower together, have breakfast and cuddle and I’m wearing his clothes he drops me off at my house. Now it’s the next day and I haven’t heard anything from him and I guess I’m feeling kinda stupid. Was it just a hookup?
