Translation "Your friend made a comment you can't get over because they noticed something you don't like about yourself and said it out loud. You have been constructing a character for your neighbor instead of accepting them as a person and have imagined what they are they thinking and then argued against that so that you could win. You do do not engage with them as they present themselves and you don't want to, because by playing things over and over in your head you have left no room for discussion."

No idea if it is accurate without the rest of the context, but that's my reading.
