So I have been talking with this girls for a while but nothing really has been happening, can anyone give me advice to advance our relationship?

How long is "for a while" and what do you want to happen on that advance?

Okay first do you mean 'girl' or 'girls' like you said? If you meant only singular 'girl', (which I'm sure you did,) then let me answer that for you. Superk is right, for how long? Let us know. And if nothing has been happening, maybe she is not ready to advance the relationship while you are. You have to learn to put her needs before yours and if she likes it like this, slow and easy, then don't feel obligated to just give it to her. You should only advance if she is ready for it. Yet, stick around, stay the same for oh say one or two more weeks, and if nothing still is happening, then talk to her about it; see what she is thinking about the whole thing. See what's on her mind about this.

Let us know how you do this:D
Much luck:)

Ask her out for a cup of coffee or tell her you like her.
