How can I figure it out?

I suspect that the wife goes to the left! I do not even suspect who she is late at work and to the girlfriends at least some friends in another place !!! How can I figure it out?

Hello. Do not believe me, I had an identical situation with my wife! And my brother suggested the site with private detectives I initially decided. Then it still could not stand, and what to do? And I do not regret anything. I really helped a lot. There are very cool detectives!
