I bought both my regular and small Loves after my husband passed away, and then my daughter screwed them on.I don't think the Love is regarded as for couples only, I just said my DH liked the symbol of it and bought me mine.
My BFF bought herself one and intends to get another!
Cartier has lots of other options IMO, I have the Love & JUC but also want a Clash and Etincelle.
I prefer Cartier's cleaner esthetic as wellI also like the Chopard Ice Cube line.
