<human>: I know this seems like it isn't really my problem, but we operated a private security company and there are sensitive files on his work phone, which has mid level encryption on it.

He has to travel a bit for some of our clients, and since it has started she has grown increasingly paranoid. She's accused him of cheating in the past which is preposterous because he's the last person who would ever do that. Now that he's gone once every 6 weeks or so she's demanded his passwords and logins to everything to "keep him honest."  This includes his work phone which has proprietary and confidential customer information.

In general I've seen her put him down and scream at him over trivial things in front of people. I shutter to think what happens when they're home alone.

She is on severe antidepressants and is seeing a therapist for a lot of issues, and she's aware that her trust issues are part of her unhappiness.

I'd never normally interfere with a friend's personal life or give unsought advice, but I'm worried how this will affect our business and his ability to do his part efficiently.

Should I tell him what I think (Which is to kick her ass to the curb?) or just let him ride it out. He's super sweet and cares for her and her kids (Not his) so he's hesitant to leave because he doesn't want to hurt them. What should I do?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Friend/business partner is in an abusive relationship and it's starting to affect our work. Should I advise him to leave his SO or keep my mouth shut?
