How important is this in building your relationships with plates?

This girl who I've slept with several times keeps asking me "I have this feeling like you're hiding something from me".

I just agree and amplify, then reassure I'm an open book, and then smirk before changing the convo.

I'm a schizophrenic so I'm naturally very paranoid and I think women pick up on that.

Should I just keep playing this angle? I've done enough reading to know that women are more interested in attractive men shrouded in mystery.
