PEBBLE is right. You should be focusing more on the "number from a solid 10", which is great, rather than trying to figure out what this approach didn't "work" with this particular girl. You were being congruent, using your personality to screen, but this particular person didn't like it. Of course you have to learn and correct mistakes, for best results over time, but with so much randomness and different people from different backgrounds behaving certain ways and wanting different things, sometimes you just have to let it go.
Side Note: Based on the situation, I'm going to assume the "married HB10" was previously married, but currently single. You should have the same assumption - if you keep up the man-to-woman flirty vibe and/or try to plan catching up soon, and she says she can't because she's married, then you'll know for sure either way.
In other words, create a whirlwind of fun from generating good state from within - which sucks people in the more momentum and emotional freedom you gain - that becomes "numb" to rejection - fundamentally the fact this bothered you, is probably the problem. Not the perceived rejection itself.
One of the problems with people in pick-up is the "batting average frame", trying to get everyone to like you (or expecting everyone will if you have "perfect/ideal" game). Owen from RSD made a
video about this (and I believe it's still one of the best and more poignant FreeTour clips he's put out). So yeah, don't be one of those people. Because you run the risk of getting too far into your head, putting too much pressure on yourself, and it counters what you're actually trying to achieve in the long run.
