Quoting ~Ice Princess~:" I would and so would he but it wouldn't get to that anyway. As for the phone, eh who cares. I have nothing to hide and neither does he."
I have nothing to hide either. As far as the phone goes, my DH is welcome to use mine whenever he pleases and i can use his whenever as well. I think what makes it different is when your SO is taking your phone SPECIFICALLY to try and catch you doing something wrong. If there is no trust, then there is no reason to continue a relationship.
