I was abused by my bio father throughout my childhood, and last year he was at a family wedding. He tried to bait me all night (stepping closer to me so that I would step back, saying things out loud near me to try and upset me, sitting directly in my line of sight even when I switched seats, trying to interact with my plus-one and others at my table, etc.). What made me stand strong against his actions before, during, and after they occurred was the constant reminder to myself that he was doing this to upset me, because he's a degenerate and juvenile loser who can't help but be a bully, even in his old age. He won't help himself and he hates the fact that I cut him out 10+ years ago, hence why he acted out at the wedding once he knew I was in attendance. Just like your uncle, my bio father knows that the separation and conditional visitations he receives indicate that what he did was wrong. Moids love abusing women, and I mean that unironically. They choose to hurt little girls and dedicate time and energy to touching and raping and otherwise hurting us and fostering the secrecy to repeat those actions. They also dedicate a lot of time and energy pushing down the reality of their actions and choices. They abuse us and expect us to do the work of forgetting for them. After all that time, why should what they did to us matter? The past is the past. Our resistance against their comfort and selective memory is an insult to them and a reminder that they are despicable, degenerate, abusive cretins who deserve mutilation and torture.
Remember what Gisèle Pelicot of France said last year during her trial against her rapist husband: shame must switch sides. The shame of the past belongs to them, not us. It's hard to let go of the shame, but it must be done, and you are the only one who can do it. How I let go of that shame is by mentally reminding myself that I am not at fault for what happened. The same cannot be said for him, who chose to abuse a child. What kind of person could choose to do that but a lowlife? I remind myself I am better than that, better than him, and not made unclean by what he did to me. He did not break me, because I am unbreakable by virtue of being female. A lot of mental and emotional strength went into seeing him at that wedding with fresh eyes and seeing him for the pathetic, malevolent, sputtering force he is. It made it easy to walk away.
