In all shortness: Girl I have sex with just mentioned that there is somebody in her life that regularly comes back and tries to get something from her (she wasn't clear if he just wants contact or more..). According to her it's happening since 5 years and only once or twice a year.
She knows who he is. She thinks he has access to her PC as he has sent her pictures that she hadn't posted online or somewhere else (they are only stored on her PC).
Offered her to go with her to the police. She refused, denied ("Oh, you know. It's not THAT bad.").

Now I'm thinking of dumping her. As I don't want to discover what else is buried in her life and don't want any disruptions in my life.. (Especially not from playpartners...)
However, there aren't any currently.

Or keep her as long as the sex is good?
I can still dump her if I see problems arise..
