Say you saw a chick on the street (stranger), and you approached and opened her. You hit it off, exchanged some contacts, some social media, arranged for a second meeting, she didn't flake, but then you lost interest on that day and never messaged her again (also, neither did she).

Well, that's what happened to me. I was recently going through my instagram (I check this thing once every three to five months, lol) and I realized this chick had unfriended me (her profile was private again).

I don't have much experience with post-second meeting responses. Is this typical? I have no clue how long ago she did this, barring the generous estimate above.

I'm curious to know if this is just normal female behavior, if I simply did not perform well enough frame/value-wise on the second meeting to lead to this result, or what to think.
