Ever? Hmmmmmm. That’s tough. Recently is easier: Juliantina, Delle Seyah/Aneela, Alex/Veronica, MarVera, Domlene, Dani/Grace (ETA2: Cazzie, lol, I forgot that too)
Some of the big forever ships from earlier: J/7, Faberry, Otalia, Clexa (ETA: And Donna/Cam! And some anime ones I totally forgot about till now) (and somewhat lesser than them, but still pretty significant to me, just not fandom-shaping experiences like the ones before: Keffy, Gelphie, Lintz, Freelin)
Huge ones in the past that because of their ending I don’t think I’ll ever revisit: Kana, Jathea
