I'm going to be the lone wolf here because for one I have no man ATM and two my belief is life is a game. People play games at school, people play games at work, heck people play games trying to be the favorite of the family or favorite in a circle of friends
If you already know the rules and have been playing for a while, then dating should come organically to you. Because by then you can usually get a clear indication of a mans intentions and where to go next. There are usually rules in place because it helps women who cannot get a clear reading of the present man or his intentions. Men and women communicate very differently and these rules help to guide women.
Just remember there are no hard and fast rules!
A lot of ladies here mentioned they met their husband organically which is wonderful. Sometimes the chemistry is there and you can get a clear reading from the mans intentions.
Strategy is necessary when you need a certain outcome or different results no matter what in life, love is no different. For example OP you mentioned an example of not answering the phone when he calls right away. For myself personally, men that I strongly crush on are a no go UNLESS I stay strict to the rules. For these crushes I unintentionally place them on a pedestal and become too needy and too open. My entire demeanor changes, lust takes over, and instead of just being my normal self that particular crush is the only thing on my mind. That is not healthy at all for me! Men I do not crush strongly on, experience a completely different version of me. The rules come naturally because I am not pressed to hear and see them at all times and I can see through clear eyes. From there I can read their intentions clearly and observe their actions rightfully.
