Take this one from me mate, if they don't give you any response at this stage then it means one of two things:
1) Not interested so just let her go and wait for her to talk to you.
2) She's pulling you on a string.
Either way, if you don't feel anything in return then best not get too into it if you know what i mean. Lingering on stuff like this just muddles up your thoughts and you start to perceive them in a different way, sometimes not true but your mind seems to think it is.
