It's not a game. Women are not like men, we don't have a "little brain". You think a guy is decent, you become friends of sorts then you decide whether he's a friend or more than a friend. This stage is the friendzone, it could go either way
Why you mad? This is good news no?
No there are three types of scenarios:
1. She's very attracted to you and there is no such thing as taking a decision, she wants you
2. You are an option and she keeps you around trying to see if something better comes along.
3. There is no chance in hell she will sleep with you, again, no such thing as a decision needed.
All of this is determined the minute she meets you. You can fukk up no. 1 though and find yourself in categorie two if you mess up. Now what you described is scenario no. 2 and no, it's not a good thing. You should throw women who consider you an option to the bushes and focus on those who make you a priority.
