I got attached to a guy online, how do I stop thinking about him?

I started talking to a guy online and although it was okay in the start, now I've gotten attached to him and I can't seem to stop thinking about him so much that I can't focus on my priorities. And although he treats me well and talks to me in his free time while I actually free my time to talk to him. Its annoying because he's trying not to get attached because of his past experiences. I'm sure its just me who hopelessly waits for his replies. It hurts knowing that it's only me who's fussing so much. And I don't want to suddenly ghost him, is there a way I can talk to him in a limited way and detach so that I can focus on my priorities?
