Search Results: making the next move

So there's this guy I've had feelings for, for as long as I can remember (5+ years to paint the picture). My feelings for him have always been on and off due to me second guessing myself and his demeanor. My gut tells me that somewhere deep down he has feelings for me too but my brain tells me I'm a fool. We don't talk much or know each other beyond peers but there's this unspoken connection or thing between us that my instincts tell me isn't one way. Whenever we interact his always making me blush and saying random things like "you have a pretty nose", "you're different to other girls" "your smile makes me...", a few years ago in class he told me indirectly he had a crush on me (he told the girl next to me very loudly) and I was trying so hard not to make eye contact with him but I knew he was staring at me to catch my reaction. Also he once sat next to me out of no where and pressed his full leg against mine for a whole period and didn't even say a word to me or move his leg away (I didn't either). But that was a few years ago now things are different we don't share many classes and the ones we do share together we don't even acknowledge each other and he's such a flirt with all the other girls and his always bragging the about shit he does with other girls with his buddies in class.

In the few years that's passed his become a such a different person but that dynamic between us is still there. When we interact it's not flirty it's more like him trying to understand me (from my perspective) and me trying not to humiliate myself. The way he interacts with me vs the way he interacts with other girls is sooo different; at least from my perspective. But anyways I'm sort of in mud now cause the years almost coming to an end and were both about to finish school and I don't know what to do. Do I tell him or do I wait till his of out my life.
