Input: Text: this just happened.  i decided it'd be super cool to message her and just shoot the shit about it, because i was so convinced.  i haven't contacted her in the last 6 months because i was so heartbroken after she left me, and wanted to give it enough time to heal before we started talking again.  it wasn't her and now she's upset and i just feel like a total dick.  i think she's awesome and we didn't have a horrible breakup, just parted ways and i know now it was for the best.  i agreed with her that it was inappropriate and apologized profusely.  i don't know what got into me, pure confirmation bias i guess.  i'm going to go bury my head in a sand dune for at least a week.
