Staggered,
Of COURSE you're feeling paranoid! Actually, I think it's only paranoia if it's *irrational* and you've been given ample cause to be suspicious, hurt, angry, and frightened. <img border="0" title="" alt="[Frown]" src="images/icons/frown.gif" />
When she acts weird and turns off her phone so you can't check it, she's hiding something. Spouses in an honest marriage don't have things to hide from one another.

Before all is said and done she is almost certainly going to get mad at you, more than once. Sometimes you may deserve it, more often you'll just be the scapegoat, getting blamed for the pain she feels as a result of her poor decisions. She may threaten to leave you, too.
You know what else? You have a choice. You can decide to live in a marriage where your spouse is allowed to lie to you and hide things from you. You can watch the distrust erode the foundation of your marriage until nothing is left but fear and hate. OR. You can take a deep breath, do the hard work, and come out of this wretched experience a better person. You'll be stronger, you'll know yourself better, you'll have the skills to be a much better spouse. Chances are high that your marriage will remain intact and be the marriage you want and deserve, too.
Regarding confronting her - FIRST read up on love busters!! You have the right to tell her in a non-confrontational manner that when her cellphone is turned off it makes you nervous, or fearful, that something secret is going on. You can respectfully ask that she make all her cellphone records available to you. You can also ask that she share her voice mail password with you. DON'T accuse her and DON'T make demands.
You also have the right to respectfully request her email passwords, to install spyware on her computer, to put a tape recorder on the telephone, whatever it takes to make you feel secure.
She may get irritated because you can't learn to trust her, or because you can't give her your trust. Remember that trust is earned, it is not given. I don't think you should say that to your W, because it will only start an argument. If she's defensive, just avoid LBs and wait it out.
