During my breakup my music taste changed drastically because I couldn't listen to any of the music I used to sing to her. I missed a lot of my old music.
Now after re-finding my personality a bit. I found why I loved this music in the first place without those feelings resurfacing.
I don't think about her anymore and what keeps me happy is that in the possible future I will be able to find a girlfriend to sing with and create new memories.
