My heart is shattered after getting dumped. Suggest me something to help me move on.

I got dumped the other day by a man that I thought I was going to spend forever with. I'm trying so hard to just dive into books so I can forget my reality for awhile. I prefer Horror books. Also dark romance but I fear I will never be able to read a romance book the same again. At this point, I'll take any suggestion I can get. Thank you!
