Want to hold his attention? Show him the real you. Invite him on a date that you'd really enjoy. Share your thoughts with him. Play him your favorite tunes the next time you hang out there. It can be scary to put yourself all the way out there. But it's the only way to show him the special parts about you that will make him want to stick around. And if he doesn't like the real you, it's time to find someone who does.
