What does this mean?

My crush hugged me yesterday and at first it was a simple side hug, but then it went from that to a full blown both arms around me, he pulled me closer and said something along the lines that everything will be okay. Then I finally told him "You are really important to me, I care about you alot, and I'm afraid of losing you." I'm pretty sure he smiled because I had to repeat it again. And I let one of my friend's hack into my fb and change my relationship status to in a relationship with my crush(because we are techincally dating, but its unoffical) and I kept thinking that I ruined everything but my crush said I didn't. And his brother told me that he talks about me ALL the time and he says nothing bad about me. What does all of this mean?
