Worst relationship on DA?

Glad to have found this community! I'm sure it's been asked before so forgive me for being new! I'm rewatching for the 5th time and I'm remembering how much Tom and Sybil's relationship annoys me. He's so pushy with her and she always backs down from him. She gives up her whole life for him and he always just seems so bossy. I also felt like they had very little chemistry. Not a favorite for me. There were more toxic couples, and ones that were just boring, but I think my actual least favorite couple of the entire show is Anna and Bates.

I've never seen a couple constantly make each other so miserable with terrible communication and fear of repercussions. They flat out lie to one another or hide important information all the time. Anna is always scared he'll overreact and he's always trying to protect her and it's even more exhausting than their progressively outlandish plots. Honestly Anna barely seemed happy once he came around and they have even less chemistry than Tom and Sybil. I know a lot of people love them and root for them no matter what, but by the third watch they mostly just drove me insane.

What couple bugged you the most?
