Look...

He likes her.... 
She is giving him the gun and ammo (about how bad things are)...
She's hoping that by giving him the keys, he raids her castle

Just victim blaming you for snooping, break her trust is bullshit. Whatever happened to talking to your spouse about your maritial issues? Fuck, what the point of being married if you have to be a fucking mindreader to know when shit is going south?
