Right person wrong time recommendations

[Julia ♧˚•༉]

I need a book with a very specific trope which is when there're two best friend that really love each other, but none of them express their feelings because they scared of loosing their friendship, and years later when one of them is about to get married or in a serious relationship, someone finally opens up about the pass and how theg felt but now it's too late. I NEED A BOOK LIKE THIS PLS
