Relationship advice

This guy I’ve been talking to for a couple of months just seems to be all talk. We go to the same school and see each other at parties all the time. But all we have is just a sentence here and there in public. But texting he’s like yea let’s hangout out or I actually like you. He’s even went as far as to ask to go to prom but then was like. I don’t really want to go though. I understand what y’all are gonna say. That I should obviously just cut him off. Which I absolutely should. It’s just harder than that cause there’s a bunch of good days too where I can imagine us being together. I just wanna know if any of you guys have been through anything like this. Help a girl out🙏🏼🙏🏼
