Hello zebdez & nice to have you as a member of Pherotalk 
Yes i agreed with jamesbonded & bubblebob in recommending TUTH. It’s good in close term relationship. Ammo also can be a second option too as it work nearly the same like TUTH. Also as jamesbonded has said you could try Instant Honesty for deeper conservation with your wife plus she will feel comfortable talking to you too. For more detailed in AMMO,TUTH or Instant Honesty, click on this link> Mens Pheromone Guide revised 6/15.
I hope i managed to help you there & wish all the best if you decide to purchase the pheros & put it to the test
