In Love and Really Hurting

So I could use some advice... I recently have fallen in love with one of my guy friends. I told him how I felt a little while ago and he likes me, but he isn't looking for a relationship because he wants to focus on school. I completely understand, but I can't stop thinking about him. I'm trying to move on so that I'm not waiting for him, but it seems that no matter what I say or what I do I fall deeper in love with him. Please help....
