<human>: seriously, it's not that you quickly decided that you like someone else. it's that you willingly let me operate under the impression that you and i were working on something and that work, school, kids, parents, life in general - they were why we couldn't hang out all that much. i accepted that as a fact and worked with it only to find out you'd been spending your time with the other person. you let me play the fool for weeks and you read all those texts and chats and heard me say those words and YOU LET ME. you didn't even try to tell me how mistaken i was, you just let me go along believing you when you knew, YOU KNEW, that i was lying to myself because i believed you.  and yes, i know i said i forgave you when you apologized for being distant and a bad friend - but that was when i thought that we were cool and getting better all the time. OF COURSE that changed when i found out - through vague, sporadic texts and an fb chat that you just dropped out of without explanation - that your reasons were not the ones you told me to begin with. i'd never been anything but kind and supportive (and you are still an amazing artist and very impressive for doing right by your kids) and this was completely unnecessary. and that, that, THAT is what hurts. ye gods, what else would you have let me walk around thinking in order to avoid an unpleasant truth?
oh, and your best friend's ex probably isn't a good choice under any circumstance.

Can you condense the text into a few key points?
<bot>: it's not that you like someone else, it's that you willingly let me operate under false pretenses and then couldn't even tell the truth to my face. thanks a fuckload.
