Sounds like a pathetic domestic problem.
If you thought your partner had been making secret recordings of you wouldn't you want to try to find any copies?
If I was cheating on my partner? Only to hide it, otherwise my game is up and will need to deal with it. But I'd never get myself into that position.
Why is she the archetype woman scorned? What has the OP. done other than record her? There is more to this story than is being told.
I've had this "archetype" (she had a number of mental illnesses) as well as a couple of people I know, without divulging information. Such people exist, they are paranoid and will create their own destruction of a relationship and manufacture scenarios which never happened and even the thought of it will make them mad, at you.
Yes, completely fictional idle thoughts will indeed make ill people believe it is real, I've been witness and personally victim of it. Even If I laugh about it now it was completely ruining my life.
She once had a dream that I was cheating on her, woke up, started to obsess about it, made herself angry at me and punched me in the face whilst I was sleeping. She tried reasoning all this later on. Ooh drama.
Basically, people can be really messed up and story's aren't always so clear cut "the OP
must have done something", maybe he didn't.
I Keylogged my pc, if I didn't I'd have come home to lots of destroyed property, amongst other things I found out it only further helped me deal with the situation on my own terms.
