Why is your husband so secretive with his cell phone and if he thinks you touched it he gets angry?

He's either doing something that he doesnt want you to know about. i.e. cheating, talking to exgirlfriend, hanging out with that "bad influence" freind you told him was no good; OR he doesn't want you to know his personal life because he doesn't trust you, even if he has nothing to hide. Either way, has time in the bedrooom lost its steam? Try to start there.... he'll forget all about his cellphone.
