TITLE: I'm [16F] having a hard time knowing how a shy [17M] feels
POST: At my school we have a friend circle of 4 boys and 3 girls. One of the boys, Alex, is very shy and doesn't really seem to talk much. In middle school, 2 of the other boys told me that he seemed to have a crush on me but I shrugged it off because I didn't really believe it. For eighth grade, he moved away (but came back to the school in ninth grade.) I made it a point to talk to him, and we would always sit by each other anyways (lunch, science class.) When I was in tenth grade, I decided I wanted to pursue online classes because my older brother was excelling in it, and I am finally coming back in senior year to my public school where he will be there. I always do FB posts every few weeks; lately I've been posting things like "I'm sorry I haven't talked to you guys but I still love you." Well 4 days ago I posted a status just like that and he liked it. The thing is... Alex rarely uses Facebook. Like, he never does. And he liked it a few hours ago. So like, is that a sign? Should it mean something? Maybe I'm just overthinking it.
TL;DR: 
Shy boy and I rarely have conversations. Haven't talked to him in 2 years, but he likes my "I love you" FB status. We're not close. Is it a sign?
