I've been in similar predicaments before, although I'm not sure if the person ever liked me, becase I never confronted him or asked him- now, I graduated high school and the chances of being able to talk to him now about it are so much slimer. I say go for it. I was in the same mindset as you are (I didn't want to ruin the friendship) but in the end, I think it will work out for he better.
