If the phone is locked then there is an A going on. The only privacy in marriage is when you're going #2. Women almost never just walk away from a marriage except for 3 reasons. Infidelity by the husband, physical abuse, OR there is someone else and they've refocused their emotions toward them. I think you're faced with the latter. You tipped your hand and she's being extremely careful now. Check the cell phone bill. Any numbers come up often you don't recognize?
Here's the deal. If there is a 3rd party in your marriage, and experience tells me there is, then your DB'ing never had a chance from the beginning. You can't save a marriage when there's more than two people in it.
