Then don't be sorry.. Not everyone is great with emotions, if he really loved you he would've understand that and if you were supposed to be together, you would have opened up without even trying.. Trust me, one day, you'll meet someone great, that you're gonna be able to be yourself with, you're gonna be able to open yourself and your emotions and you'll see that person fight for you, no matter what.. Don't miss someone who didn't even try to fight for you, I know it's hard and I have no place to tell you that, but you deserve so much better, so miss someone that's worth missing, but I can guarantee that, that person would never even give you reason miss him. :)
You're also very pretty and i'm in love with your glasses lol.
