I think this girls problem is she wants to be with you and thinks about you as if you two were dating but she has a hang-up on the whole title of a relationship (associated with commitment problems)  well if she wants space then let her call you, you can answer when she calls just don't you do it.  You let her call the shots for a little while.  Since she's telling you one thing and doing something else, leave it up to her to decided when she wants to have space and when she wants to be with you.  The only thing I can say here is you can either go with the flow because she may relaize she's happy with you, or go the "no contact" route and move on.  But those are only options right now.
