from your post and what I see,
she probably wanted to use you, you seemed like a pushover, sort of proved to be one, soon as the frame turned somewhat romantic, she expressed dis-interest and backed out
there could be a million other things, but what stood out was, blah blah blah, my car, she liked that shit, gave her a ride, hellz ya, she hits me up
her:blah blah blah, come drive me in your car
you:kk babe anyting you want babez
her:blah blah blah, you gonna get a better job for more monies?
you:you know it babez, anyting you want for you babez!!
you:hey babez, if it's not too much trouble or anything, and you don't have anything better going on, could you pretty please with a cherry on top bless the lowly me with your presense one time?, I have a nice car
her:you mean like, beyond me and your car and you?
you:yeah pretty much, but I also do other stuff for you
her:FUCK NO, HELLS TO THE NO, GTFO NO!!
that is the way that conversation seemed to translate, this is pretty standard shit imo, you played pretty easy to get, not like I am advocating playing hard to get or anything, but it was sort of like, she says jump, you say how high?, not an ounce of screening went on with this girl, first meetup she runs away?, why even waste time on this girl, you could have found this out way sooner and not invested any of yourself into her
also the problem was not plausible deniability, in no way did he even suggest having sex, and the frame sure did not seem to imply it, possibly she had sexual intentions but this guy was 100% a-sexual to the max
her: like your place?
him:nah, not like my place, I mean ya we can go there, but you know... bars and stuff and restaurants girl...
