I (27M) broke up with my girlfriend (26F). We have been together about 4 years and broke up about 4 months ago. We connected through our music and she has always told me she fell for me through my music. We loved each other deeply but certain things drove a wedge between us, and here we are now. I sort of avoided the break up. I accepted it without really fighting back. But I recently sat with myself and deeply regret it. I realized I was avoiding my feelings for fear of the pain that comes with grief. I couldn't sit with it. So I reached out one last time. I wrote her a letter apologizing and telling her I still love her, but I understand she will move on, and I will always be there for her if she needs me. At the very end i hand-drew a working spotify code to a song that mirrors our relationship. Im just curious, how would you receive the code? Is that too much? Do you feel its romantic? Just wanted to know people's opinions. I personally believe she will think its the most romantic thing in the world next to actually playing her a song.

tl;dr
How would you feel if someone drew you a spotify code in a letter?
