pretty much, women have been used to having their way with men for so long and knowing that most will accept it if they are pretty or "caught up", or hoping for vagina, that they can pull these games and disrespectful actions, or flake and knowing more than likely dude will say allright sure and take her out next week, or when she's bored. There so used to it they get so angry if you call them out, or just sever the ties.
And what's worst is they will flip it on you if you try and call them out, wow your insecure, wow you have issues bla bla, that's why I just act "dumb and oblivious", and get on with my life.
Yeah, women constantly play little games. If you let her reschedule, she feels that she 'has you' and you are in backup territory. Oh, I got this dude for dinner next week. A woman that is really feeling you will break dates with other dudes to be with you. When you're on the wrong side of the equation is when you get that, "Oh, I was busy with such and such."
You're right in that it's no use in arguing with them. Better to gracefully eject. "I'm free next week." "Oh aight."
Something I've found is if you don't force a woman to think of you as 'her man' or as someone she'd like to date, you're going to get put into buddy category or meals on wheels category. If she can keep on talking to you without her having to make a move and see you, or if she can reschedule dates, you're going to be in a bad position.
As a man you simply have to approach women you want as your woman as someone you are dealing with on that level and never 'as a bud' or conversation homie.
