Hanging out is a good first step, it can also be a gauge to see if the feelings are mutual or not. You can only really tell by the way she acts when you two are together during your "date".

I don't know.
I do that with my bestfriends but we don't see that in a romantic way.
I am just used to calling my close ones, baby, sweetheart, etc.
I don't think it's a date. :)
