How would you feel if your spouse spied on you?

And their doubts turned out to be true. Would you be ashamed of whatever the wrong thing you've been doing? or would you be pissed off that s/he looked into your stuff and focus on that point and be upset about the invasion of your privacy?

I myself will have no problem at all when my future husband looks into my phone (cause there shouldnt be any secrets, i might even ask him to check my phone if anyone called or texted),and when couples have an issue with their partners holding their phones, that just raises a red flag.

Now, I understand spying can be wrong, but only to an extent imo. I mean i know few wives that found out about their cheating husbands when they spied on them, and they didnt have kids yet, so it wasnt too late or extremely complicated to get a divorce. It wouldve probably been messy if they didnt spy then and found out later.
