Accepting what is and moving on when you have no power is the only healthy option. This option requires imposing self-control over behavioral and cognitive aspects of the self. This option is the only one that works. Angry people tend to impose self control at the sensory level and not impose self control at the level of action. This unhealthy state of affairs needs to be reversed.
Passive acceptance is necessary at the level of sensing.
Self-control is necessary at the level of action. The angry person implicitly, and falsely, assumes that the conquered partner can sooth and fix their internal pain, boredom, emptiness, anger, whatever. Nobody but the self can. Read it and reread it. Then read it again.
