Unpopular catherine opinion

Catherine was justified to be mad, angry, etc. But Susan is also wishy washy. I know for a fact I'd be just as mad being a placeholder.

Specifically in s6e4 when her wedding cake with Mike was used to cater another brides wedding. Im totally on Catherine's side. Yes she def needed help but Mike and Susan ruined everything for everyone. All the time. My Mike and Susan hate goes so deep.
