Can someone offer some words of wisdom?

Ok, here's the deal-many years ago when I was in middle school I had a major crush on one of my teachers. I'm pretty certain he liked me too, as a student and possibly more, but never really did anything outright he wasn't supposed to do. A few months ago, I found him on facebook and after hesitation, sent a brief message just asking if he ever used to teach at so-and-so school (just making chitchat). I thought it was innocent enough but anyway the best I can tell he's been on a couple times after that but so far hasn't replied. So, I guess he could have forgotten after all these years, that's understandable, even though the year I had him was his first year of teaching. But I'm assuming the more likely prospect is that he read it and is ignoring me. I don't know why it's bothering me so much; I hadn't thought about him in a long time until a few months ago when my friends and I were reminiscing and now I can't stop thinking about him. He was a great person, friend, and teacher. I just miss him and would love to have someone like him in my life again. I know I'm being a total loser...
