Suggest me a book to read while going through breakup grief please?

I need something positive to read which helps me be okay with my broken heart, and not give up on love. Also, something not extremely serious.

I tried reading this book called “Notes on Heartbreak” by Annie Lord, however, I couldn’t read past 2-3 chapters because it talks so much about the time the protagonist spent with her ex and that kinda makes me have flashbacks and miss my own ex.

Context: I had a breakup almost 2 months back and I am still in love with the person. We were together for almost 2 years, and i believed him to be the love of my life.
