Has this ever happened to আপনি and what should I do?

I went to a camp for five days and while I was there a boy who I have hated since kinder was in my bunk house. While I was there I started feeling really weird around him. I would blush when he looked at me, my legs would wobble a bit if he spoke to me. Later on the last দিন we have a tornoment where all the bunks compeat. The boy being who he is (strong willed, somtimes mean, handsom, and muscular) took off his শার্ট প্রদর্শিত হচ্ছে his musels to প্রদর্শনী other teams so the would think they could not win but I nearly fell flat on my face. I only relised then I must like him. What should I do?
