My father has a serious mental illness. According to my mother, my father's family never disclosed it before their arranged marriage in the 1980s.
My mother came from a poor family and had lost her father. From what I've seen and what she's told me, my father's family constantly criticized her—her skin color, the way she dressed, the way she spoke, etc. Looking back, it feels like they were trying to keep her confidence low so she wouldn't question the marriage or consider leaving. It affected her so much that she eventually took personality development classes just to rebuild her confidence.
As a child, I always knew my father's behavior wasn't normal, but because of childhood trauma I became detached from people and never really understood mental illness or questioned what was happening. I didn't fully realize he had a serious psychiatric condition until I was 27.
When it finally clicked, I was furious. I went to my father's younger brother's (Mr.Sun guy) house and confronted my uncle, my father's younger brother(I'll call him "Mr. Light"), because he was the one who handled all the marriage discussions. In arranged marriages back then, the bride and groom often barely spoke before the wedding, so I hold him responsible for what I believe was the concealment of my father's condition.
I threatened him in anger but never became physically violent or assaulted anyone.
Now I'm wondering whether I overreacted. Part of me feels my anger was justified because I believe my mother was deceived and suffered for decades. Another part of me wonders if confronting an elderly man years later accomplished anything.
I still live with my parents, so this situation is still part of my daily life.
Did I overreact? What would you do in my position?
TL;DR: I found out at 27 that my father's serious mental illness was allegedly hidden before my parents' arranged marriage. I believe my mother was manipulated and emotionally belittled by his family for years. I confronted my uncle(his younger brother), who handled the marriage, and threatened him (without any physical violence). Now I'm wondering if I overreacted and what I should do going forward.
