Crush help:(

Ok so there’s this guy I really like but for some reason we have always hated each other. Anyway I started doing this sport that he does (like 7 months ago) and for the first couple months we totally ignored each other but then I realized he was a way better person than I thought (and pretty hot) and developed a crush and he started acting nicer too. The only problem is it’s clear we like each other but neither of us can break the act that we hate each other and we only talk with snarky comments.

I guess I’m just saying I know we like each other but neither of us want to/can admit it. How can I change that without doing anything too drastic?
