Question about acquaintance

I tried to get to know the girl, we leave at almost the same stop on the way to work, the first time I came up and asked for a phone number. Ash Peter did not give, but gave only a page in VK, but there is no information about me there, wrote in VK neither an answer nor a greeting, came up a second time saying that you write when I cannot answer (why then give VK) and Allegedly, her young man comes to work for her, came up for the third time, the same thing, they say, her boyfriend is nervous, and so on. From memory, as I remember, I kind of asked if she didn’t like me anywhere, she replied that I don’t mind, but only in the morning no one was watching her. And what am I to do, I am a layman in this matter, and why the dead-end development of relations, I personally do not see the future. Well, in fact, the question itself is to achieve your goal or not, what is the psychology of the girl, otherwise the point is already starting to play.
