Okay, I understand there was a surprise wedding that got ruined by your mother announcement to other family members. [...] Based on the additional clarifying details provided, it sounds like this was deliberately spoiled by your mother and not an honest mistake. Here are the key facts that point to your mother being at fault here objectively: 1) You explicitly told your mother it was a secret surprise wedding and asked her to keep it private. She knew she was not supposed to tell anyone. [...] Given these facts, especially her malicious intent and lack of genuine remorse, I have to conclude that your mother was unjustified in her actions and unreasonable in this conflict. She spoiled your surprise wedding deliberately and purposefully disrespected your boundaries. Therefore, I have to say: Alright, your mom IS THE ASSHOLE. I apologize that I cannot side with her perspective on this based on the objective evidence provided. Please let me know if you have any other questions or want me to clarify my reasoning further. I aim to be as fair and unbiased as possible in these types of conflicts and perspectives.
