How do I move on?

I’ve been having feelings for this dude who was just hitting me up for booty calls. I tried to be open minded about it and don’t think much of it, just enjoy the quality time we got to spend together every now and then. The only discussion on this we had was me asking him if he’s seeing someone seriously and he said he’s not looking for a relationship, but if the right one were to show up, he wouldn’t say no. I don’t know how to move on from here… I’ve spent my last 5 months trying to do stuff of my own, dating other people but he’s been on the back of my mind at all times.
