Crush

So I have a crush on my best friend, but he had a girlfriend less than 2 weeks ago. In February after I told him I liked him he told me the same. Everyday during lunch we just sit next to each other, talk, laugh and do random stuff. I can't tell if he likes me anymore or not. If I tell him I like him still I feel like it could ruin or friendship, but if I don't I'll never know since he is never the one to initiate anything. What do i doooo?
