Discuss issues with the behaviors, not of the person.
And I presume of course that your shareholders contract defines how this situation will be handled in nthe event that the conflict cannot be resolved?
Our contract does not define how things will be resolved in a conflict. Basically we end up deadlocked and nothing happens until one capitulates. This has resulted in absurd scenarios that I would be too embarrassed to admit.
If we manage to survive this crisis I there is a lot of work to do in order to fix things. There is a lot of built up damage.
Is that even doable for a non marital relationship?
I wish I done that with my ex-partners. Sometimes an objective and impartial third party is exactly what you need. People can get dug into their points of view and be quite honestly unable to see it any other way - until a third party points out the elephant in the room.
