Vocab, Anyone

Guys, I need your expertise. I am looking for a word. I need a word to describe a relationship with a person that is romantic in nature but not dating. Crush doesn’t work because the other person (people) knows. Friends-with-benefits doesn’t work because the relationship(s) is more than friends.

I feel like there must be a word. I don’t even care is English. It just bugs me that I there are people in my life I can’t explain my relationship with without giving a whole paragraph.

Anyone got anything. My vocabulary has finally failed.
