Well I did a similar thing just yesterday and the main reason behind that was that, well, we used to be friends and then I had a crush on her and then I didn't, in all this time, I never did tell anyone really. What happens next is that something related to both of us happens and I just wanted to tell her about it but because of all this that happened in between I just straight up seemed weird both the times I tried to communicate with her. So yesterday well I wrote her a song simultaneously apologizing and admitting my past crush and I'm just happy that it didn't go bad. She said she liked the song and all and a similar response to the one that OP got but since that was what I was expecting I was actually happy about it. Now reading all the comments here I just feel dumb
