Hello @DarkLight,
I would like to start by saying, that the first thing we addressed was love and the longing for reconciliation that comes of love. I think this should be the starting point, as you so well expressed in your OP. And I will say it again: as so your perfectly echoed the words of saint pope JPII himself. And the reason why I think this of such important is, because it allows a stepping stone, the laying of a solid foundation from which to build on. Where there to be any misconception regarding the longing for reconciliation it would contribute to nothing but confusion.
The second issue which now emerges -and was already present in the OP- is: Anger.
Now, you give Anger specific circumstances and, I will address the circumstances as I build towards addressing Anger.
There are countless expressions of Anger. And Anger immediately upon expression, manifests in forms: “getting shouted down”, insult, injustice, vengeance, threats, selfishness, etc - these are the “overt” forms. But there are also “covert/veiled” forms to express anger: “the could shoulder”, blaming, “silent treatment”, etc…
Thinking, now, exclusively within the “field of morals”: Anger is one of the 7 ‘Capital Sins’ which are not by definition ‘Mortal Sins’ or ‘Material Sins’. Because, the 7 ‘Capital Sins’ haven’t yet materialized, they are ‘States of the Spirit’ that upon expression take a material form, thus materialize, becoming material sins - consummated sins. Sins against justice, sins against charity, sins against humility, one single act (expression) of Anger can simultaneously sin against several commandments and virtues.
[If you haven’t looked at the check list of expressions (passive/aggressive/assertive) of Anger, I would very much recommend you do so here:
Dichotomies of anger expression on wikipedia].
Now, the circumstance of Anger you describe is taken over time. There was Anger in the past, and in your present you face the future perspective of more Anger, whilst presently dealing with the ghosts of Anger past. Expectation management is key here. [I will address it further down the thread when I speak about “habitus”.]
But you have to break this infernal circle - a vicious cycle.
There are people in the world that aren’t given to Anger. You can expect goodness, a kind word, an act of justice, benign dealings, and love.
