<human>: Basically, we all went to the same university/college. She has moved back home and really won't see 90% of the people she met in university.

She has broke up with her BF and her BF has moved on and slept with other girls. She wants to move on too but she knows as soon as she moves on, he's going to go psycho and try to blackmail her with nude photos he has of her. He's always been sneaky with his computers, 
passwords, etc. She just doesn't trust what he might try to do if she tries to move on too.

What should she do to move on?

Give me the gist of the text in a nutshell
