Does he have a crush on you?
A crush is complex. First there is the friend-ing, the secretly-loving, the major crushing, then the making the move. Will he make the move? You never know.
The move. It requires talking and confidence. You need to be comfy in your own skin. If not, how the heck are you gonna ask a girl out? A simple phrase, like, "Whatcha doing Wednesday night" just doesn't cut it. It needs to be unique, perfect.
