This was really engaging - I've also had friendships like this one, and the thought processes felt very similar to these. Being stuck in a cycle where you're not sure whether to confront the other person over things that are lacking, or whether it's better to grin and bear it in the hopes that it's nothing. It's very thought-provoking and emotional to play; well done.
(Also, just FYI, at one point the text says "...safe for her musical prowess," which I believe should be "save for her musical prowess"?)
