First off, if there are no secrets this or these episodes should have been immediately reported to your wife in order to be cleared of any possible accusation in case she had found out by herself that something dodgy had taken place.

This really calls for further investigation, at this point you'd better tell us your version of the events and it will be considered as a form of collaboration.
Definitely doesn't work for me, mhead.
Why would she care about these irrelevant events if Slash is being completely honest? There must be some trust issues, maybe something happened before that's making her unsure of Slash's honesty?
