I have this crush

I'm asking for help here but I have this crush. I'm a gay male and I don't know what he identifies as but I know at one point he was questioning his sexuality, he's in the GSA for our school and he especially 'acts gay' around me. I don't know what to dooo I wanna tell him how I feel but idk what he thinks of me n shit. EDIT: Send help idk how to flair on this subreddit
