Can you suggest books for going through breakup

So, I am 27 years old and had a devastating breakup yesterday with someone who I thought I would spend the rest of my life with. He now wants to have a break. I don’t know what that means, but I think it's probably over, and now, for the next month or so, I'll live with hope and then get my heart broken even more badly. But I don't know what to do about that and that's why I'm here.

Books have always been my escape. I usually read romance, but I don't know if I could handle that now. But I also can't read non-fiction. Some of the recent books that I've read this month and loved are:

The wedding people

Malibu rising

Carrie soto is back

Piranesi

Jade war ( The Greenbone saga as a whole)

Yeah, that's it. I just want to come to terms with the fact that I've lost all those dreams and the future that I imagined. Thank you.
