I would bet this is much more common then you seem to think.
Your job isn’t a marriage and the analogy falls flat. If you’re having enough communicative difficulties that you’re considering failure, then you’re already enough in the shit that one or both of you need to move on.
Of course not. You work through problems when there's value on the other side of the problem, and communications problems are just one class of problems that may crop up in an otherwise highly valuable relationship. You hire people to help you solve other issues you don't have the experience to solve, don't you? The same SME is valuable in communications.
That's right - and how do you think you should go about approaching those issues?
FWIW, I think therapy is awesome and should be embraced by more people. Probably a good thing for founders to have their own version of it. Renowned therapist Esther Perel has (had?) a podcast called How's Work? where she mediated conversations with business partners.
