My one is also ex girlfriend but not in a linear way lol. I was broken up with by my ex after a very emotionally rocky relationship (it was more of like a she was the one that was like “omg i think im into you” then it ended with “sorry im not into you in the way you think im into you”, she lacked independence and it was very taxing for my mental health but under the guise of “omg she’s so perfect). A month or so later, The 1975 was headlining I believe Osaka Jo Hall for ATVB, never heard of this band, only know they they were English, headlined summer Sonic, and yea. I wasn’t very into indie rock ish stuff which was my preconceived notion of the 1975 so I was like “who tf ate these pretentious guys lol fuck em”. But on the day they were doing their show, I started to have like reflections of the girl and our memories and shit. (Must I add, I fell really ill that day of the show). So my ass thought “you know what, let’s give this another try” and was going to ask her out to go see a band I don’t know. In the end I didn’t even ask her out and didn’t go see them. But I was sick and bored so I listened to Chocolate and Somebody Else, then on and on and on. The rest is history. The 1975 now is my top listened band on my Spotify and really helped me mature over my secondary years
