Checking spouse mobile phone

Its so tiring to be uptight about someone, what more someone who is living with you forever. Our phones can be unlock by each other thumb prints. I guess its gives me securit6that way, and if he really wanna play punk, he will be the one going through the trouble of deleting messages before coming home, asking the third party not to text, he will he the one being uptight. But for me... I can just sleep peacefully. Coz, i believe the paper cant wrap fire for long. It works both ways, since he can unlock my hp too!
