Have I screwed up too far, am i overreacting or what? I am so confused its pretty sad.?

I met this amazing girl, totally smitten with her. Unfortunately i talked to her friend more than her. friend was always telling me stuff, trying to help but it usually didnt. we became close but never had a real dialogue - but we were both happy. i know she felt i tried too hard and i thought too much - yzing everything she did. i felt she was one way but her friend always confused me and i never relaxed. eventually she started pulling away and told me she didn't have time to be in a relationship, couldn't make me first in her life, and i was confused just a few days before she was mad at me for not spending time with her. we talked and i have no idea what is going on anymore. she doesn't call, text or respond if i reach out to her. she always tells me to only go off of what she says, and not read into things. so because she doesnt contact me do i ume she doesn't want to talk to me? because she doesnt say stop that she needs time. i dont want to walk away or bother her.
