My wife (who I am sure is having an Affair) asked me last night if she could get a job?

I about flipped out. I had always asked in the past if she wanted one (I know kind of shallow) she always said, "I would never"! Now last night she asked me out of the blue if I would be okay to seek a consultation!!! Listen I haven't broke it to her that I am on her trail. I found out the guys first name, yesterday morning, I put a recorder by her vanity. I mean she thinks I will pay for him to have a good time. We've been married 12 years and I really have not been thinking of divorce, I just want there to be no mistake on my part. Should I buy them or tell her I know somethings up?
