I’ve finally had a revelation that once a relationship ‘goes bad’, meaning even if the closest of loving people have a first-time conflict, there is no repairing it. One would think if both people truly care for each other and apologize and change the offensive behavior, the relationship could restore. Sadly, IME this has never been the case.
If one wishes to keep some relationship with that person, they have to act like everything is fine, grin and bear it. Otherwise, they can end the relationship, moving on to find others who will treat them right.
I’ve wasted so much energy trying to repair relationships gone bad. It takes two.
