Ok so I am on mobile please don’t hate me

I have been dating this one girl for about two months now and it has been overall fine.  Whenever we go on a date together, she is really talkative and we both seem to be engaging but whenever I text her or call her she either waits to respond or responds negatively and seems annoyed.  Also, whenever I see her in my classes she almost seems to ignore me at times.  I looked back through my (few, actually) texts with her and realizing that I was starting everything we did.  I always began the conversation, asked if she wanted to go on a date, etc.  Being the pessimist that I am, I psyched myself out thinking that she didn’t really like me and thought that she only hadn’t broken up with me yet because she didn’t want to seem mean.  So I decided to try something.  What if I just didn’t interact with her at all and wait for her to take initiative and do something.  It has been four days now please AITA?
