Unfortunately, there are no right or wrong answers when it comes to love.
There is no rule book that says women act in a certain way. Some women play games, some don't. It is the same for men. All you can ask is that she be honest with you, if she isn't interested, get her to tell you that, not just 'let's try next week'. And in return you be honest with women, if you are not interested then let the woman know. There are ways of letting people down nicely without hurting their feelings but also making it clear.
There are thousands of women out there, don't get hung up on the women that don't get back in touch, look at yourself, dust yourself off and get back out there.
This is all trial and error; you will find the right woman in time. Good luck!
