Cheating in relationships starts when you're hiding something from your spouse. It may not necessarily involves the opposite sex. It may be finances, relationships, information, etc.

You're also cheating when you have loyalty to any other person or any other cause other than your spouse.

In line with the above, you can answer the question of your wife cheating or not.

Which way forward?
My Opinion
You don't need to trail or investigate her. If you do, the worst case is for you to catch them in the act, if that happens what will you do: it will just hurt you more.

Remain the faithful spouse you are. Yes remain faithful, cheating in return to revenge will create a generation of cheaters. Show her more love.

Seeking the kingdom of God should be everyone's goal now and not indulging in activities that will be drawing you closer to hell.
