Is it necessary for a wife to check her husband's text messages?

A clean hand wants no washing. Let her see it if she wants, unless you have private money and don't want her to know. Besides, if she looks at you, won't you look at her? !

My husband and I just looked at each other. I'll look first when his cell phone rings, and he'll look first when my cell phone rings. It's nothing. Husband and wife should be honest so that there will be no contradiction.
