I don’t know what to do

So am gay and one of my friends is straight and I think I don’t know why I feel this way. So back in 2025 I told one of my best friend that am gay.and since that point whenever I see him my heart feels punch. I never felt any type of feelings towards him and it only been happening since I told him. I know his not gay and had rejected 2 gay people in the past. But for so reason I feel so thing to him . Even the last time I talk to him he told me to shut up and instead of telling him off or something like that I feel weird even though we were just playing around. And when he makes fun of me I feel a lot harder than when someone else does it. I know I don’t have feelings for but I it becoming harder to ignore. I wish I never met him and it not his fault what should I do please help.
