What i would do in this situation , regardless of if this is just a shit test where she wants to see if your gonna be like a little puppy asking her "whats wrong?, are you mad at me? why are you mad at me" or if you actually have pushed her away. This could be a sign of attraction and she might be testing you to see if she should be attracted to you. So Regardless of what it is, i would turn up the cocky and funny. Like bust on her, tease her and keep a playfull vibe and if she still acts cold, ignore it and keep going. If shes interested, she will love that and if shes not, this might actually get her interested
If you see her somewhere random you could tell her "omg are you following me? omg are you one of those stalker girls?!?" with a smile ofcourse
