<human>: Condense the text into a few key points

I was raised in a conservative home with my brothers and parents. My whole family is very mild-mannered and Christian, and I've always considered my dad a straight arrow. I'm heading off to college this Fall, and my dad decided it was time to tell some family stories. Appparently my uncle was really into cocaine in high school. After he graduated he became a skeleton and couldn't hold a job or go to school. My dad talked him into talking to my grandpa, and eventually he agreed to seek treatment. Now he's a software engineer and makes six figures. Also my dad dated a cocaine addict for four years. The last three years of the relationship were him trying to get her off the drug. He paid for her treatment, went to therapy with her, bailed her out of jail and saved her life over and over. Once she became stable, the relationship ended. Through all of this, my dad today has never used cocaine or any other drug. I'm oddly proud of him.
<bot>: I always thought my family was as straight as an arrow. Turns out cocaine can affect anyone. My dad is a saint and potentially saved two lives.
