What to do now?

I am actually curious what this means. Long story short. I asked a certain girl out, on a date. She was kind of hesitant, did not give clear answer, said she would write me later about date but eventually never brought this subject up. Apart from the dating part, we would message each other from time to time, nothing serious. After some time, even though we kept in touch, I noticed that she unfollowed me. One in one, meaning that she had zero interest from the start. Up until few days, when my friend happened to be called in as a substitute, at the place where she works. I bought box of chocolates and told my friend to give it to her, which would mean sort of "hello" from me ( I have no idea why I did it, yes I maybe have been wrong) as I have not see her about a month or so. Obviously she wrote with huge thanks, started following again and after few hours she unfollowed again? meanwhile we actually write each fairly frequently. Is it her way of saying like "fk off" or is she simply playing with me? Don't get me wrong, I don' really want to sound childish bringing all this follow/unfollow stuff, but unforutantely I don't have a luxury to see her fairly often.
