As far as I'm concerned, anyone who thinks that snooping is the road to marriage and happily ever after has mental health problems.
If she did not trust him, she should have left him.
I think you have mental problems. She did this, with alot of suspicious behavior going on......So she WOULDN"T make the mistake of entering a VERY UNHAPPY marriage.
Shit you told her she should just ask him and take him on his word. So your advice was basically just Marry the guy anyway, he told you nothing was going on. Get over it you paranoid freak.
