I'm going to track my wife's location via her phone
Why would you want to track her?
So she won't be cheating on me with other guys.
Tracking someone without their permission is a violation of trust, and can end up with her trying to divorce you because of you spying on her. Instead of trying to track her, why not just try to ask her if she is cheating or not?
It's none of your business.
It's also none of your business what your wife does but you're tracking her.
