Unrequited love/Failed romance moving on book suggestions

Suggest me a book that will make me cope seeing my crush 2 meters away everyday for the rest of this year and having to ignore her because we didn't work which is super hard, so I want something that will shift my perspective, help me move on and cope with the current pain (I have been in love with her for more than a year and a half and we got closer In times and further times but it seems there is no coming back from this one. It's permanent) .The Witcher isn't cutting it lmao. Harry potter won't wish away my feelings too
