It sounds like you already know this. Ofcourse, those in love or normally the last to find out, arn't they? Is this all your wanted? For someone to confirm this for you? Or would you like advice on how to go about getting him to open up?
If you want to know how to open a guy up, all you have to do is ask him about himself. Music and sports are to great topics. If you really want him to talk for hours, ask him about Music and/or sports. That is a great way to open up even the most shy of guys. You will learn so much about him, and he will walk away thinking you had a great conversation, too, which makes him much more friendly to you ,and more comfortable around you.
