Perhaps we need to break it down.
You don't see how because the women you've experienced don't, in the long run, fit. Nothing wrong with that.
Then you are weeding out women who aren't right for you; this is a good thing.
Don't try to impress others. Just follow your ambitions. Women will always be impressed with that, on whatever scale you do it.
So unplug from all of that. There is room in the world for people who don't partake in all of that junk, contrary to perception.
You are walking down too many main streets. Take some less-beaten paths. It looks like you're already willing to travel around, which is good. Also: Take a break from women from time to time.
You are qualifying and weeding out - again, a good thing. You shouldn't blame yourself for this. If you think you are being flakey, then be more up front and tell the chick you had a good time but don't see this working out. Would that more people did this.
Counterproductive is forcing something that's not right for you or for her, supplicating, or reframing yourself for her. If women are becoming adversaries, that is a problem. A good woman doesn't encroach on your life because she wants to sabotage your dreams. However, you do have to be a little firm, like telling a child it's bedtime, when you need time for you - and you need to do this early. If you simply don't have the time for something serious, that's your prerogative, and again, a good thing if you accept it.
Well, you came to the right place!
