You seem to be almost stalking her every movement around.

I mean, seriously? You're tracking exactly what stores she went into in a mall? Seriously?

On the other hand, if she is manic and you have hard core evidence of it, then you should seek couple's counselling to address it. I know you said she had a relationship with her ex - how do you know it was an emotional affair? Did she tell you it was an emotional affair? Or did you just dub it on your own as an emotional affair?

As for the pornography on the iPad. Nope. Harmless. Doesn't mean she's cheating.

As for the Craiglist. Well yes. That's the only one I'd say look into.
