why are they going around in circles?

I dont know but todays episode with her threatening to cut off her wrists - puts me off. I mean what the hell are the CVs do0ing?? they are making both the main leads look like basket cases. Im sorry I know a lot of you will be upset - but what the hell is happening?
He suspects her .. he suspects her not .. he suspects her .. he suspects her not ...
she loves him .. loves him not ..
she will take revenge ... or not take revenge ...
The story doesnt seem to be moving - since the last few weeks - we dont know if MB is playing a game ? or is still emotionally involved...
Can some one tells me pellleeej .. 😕
