<human>: Can you condense the text into three sentences or less?

My Aunt has been dating this man for a while now who we'll just call her husband. Things have been going great, however a few days ago a news report broke out of a deputy exposing himself in front of a coworker and being arrested and fired. Turns out this was him. The entire community knows about this.

When my mother received word of this she informed my aunt he was not to attend my brothers graduation. My aunt took this extremely hard considering she paid for alot of my brothers books, clothes, SAT exams, and even his graduation robes. Wanting to stand by her husband, my aunt decided she wound't attend as well.

My brother is heartbroken she wont be coming, the rest of our family (including myself) is disgusted with her rationale for dissallowing him at the graduation ( she's worried about people talking about her). She is a person that only cares about what people think about her. It makes it very hard for me to side with anyone in this. I think what my mother did was reprehensible and want to tell her off but at the same time i don't want to cause any family drama.
<bot>: Uncle cheated on aunt and it became very public. Mother is a raging bitch and dissallowed him from attending brothers graduation. What do?
