<human>: Okay, a little background: 

We've been friends since middle school. We were really close up until
my senior year/her sophomore year of high school, at which point
she moved to be with her dad. Her mom and stepdad were extremely
unsupportive, abusive almost. When she lived here she 
was pretty depressed and seemed obsessed with the idea of getting
away. Before she left we promised each other we'd still be best 
friends but of course we grew apart. We've talked sporadically over
the past couple years.. Then last year she came back home for a 
visit but after she returned we still didn't talk a whole lot.

Earlier today, she posted a cryptic status about something bad 
happening at her house and that she had to get away. I messaged 
her and she told me what happened; that he's been molesting her for
about 3 years. I feel terrible that I didn't somehow know and now I 
feel like everything I say is dumb. What do I do???

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My best friend confessed to me that her father has been molesting her and I feel like a bad friend for not knowing what to say.
