<human>: Give me the gist of the text in a nutshell

Long story short...This girl I just became friends with (~3 weeks) was visually perturbed that I wasn't speaking to her very often, much like before we became friends when I saw her noticing me. I was being a bit childish at first, but last week I made attempts to speak with her only to to be foiled by her bitch of a sister.

Since the verbal method was not working, yesterday I sent her this message: "I'm not sure how I fell out of your favor, but whatever it was, that wasn't my intent and I'm sorry. I'd like to know where I stand with you because, honestly, I'd like to learn more about you as a person and I hate that I may have messed that chance up.".

Of course, I haven't got a response and I know for a fact that she has seen it. I think this is bullshit that I cant speak and when I attempt to uses messages, I get blown off. How do I not give a fuck about this.
<bot>: I realized I may have messed up a good opportunity and I've tried to correct the situation but am talking to an unresponsive female.
