Women who suspect their DH / partner of having an affair who decide to check their phone need to mags endless excuses for doing so ie
I have never once done this before
Or
I know this is wrong but I decided to check his phone. I know I shouldn't have but....
Really? Surely it's just common sense in these circumstances to do so? Why wouldn't you? Particularly given than 9/10 people seem to find out that their 'D'H is up to no good!
