help I'm perplexed

Sophia

So I have this really good guy friend and 2 years ago he told me he liked me. But I didn't like him. Lately these past few days now when I think of him I get butterfly's and I feel like I like him. But when ever I do see him at school and hangout with him I don't feel that way. Do I like him or do I just like the idea of being with him. Because I'm not sure if I truly like him like that. I want to tell him I like him, but honestly I'm not really quite sure I should.
