Think I got rejected by my crush of 4 years. How to move on/what to do now?

Asked the guy I liked out since the first year of high school. Got rejected I think? He’s really really nice to me and then he’ll completely ignore me so I asked him if he liked talking to me and he said “I guess” and we haven’t talked since then so yeah. What to do now, how to move on, where to find cute guys (none of them ever truly seem to compare to him ie. I’ll have another crush but I’ll still like him more)?
