Books about queer yearning guaranteed to make me cry?

Looking for a book similar to Chloe Michelle Howarth’s Sunburn or Phillippe Besson’s Lie with Me.

I need a heart wrenching piece of fiction feature a queer couple that can’t be together because of external factors. Something that’ll break my heart in two?

I’m worried I’ve read all I can in this genre and won’t be able to find anything else good again.
