Ok I’m not sure if it’s me or if its her

Ok people do not believe me when i say I don’t pursue a girl if I see her interesting and want to talk to her. For me I just wait  for opportunity and when I see an opening I take it because I don’t wanna waste time because we can all admit that rejection is a bitch. But this time I took the chance and said imma get some balls and do something. I took the chance and we spoke and I gave her my number and stuff and said she was gionna call. I thought at first ok bullshit but we speak on average and in class. Now I’m starting to think if she is waiting for me to extend more and constinually talk to her for interest but how can i shy person approach another shy person? (yes I said it I am shy) idk but I already put out interest and is it wrong for some confirmation? I might have to try AGAIN to see if she is interested because I don’t want another to slip threw my fingers again
