The Clues are all there and what do you do with it?

I can't believe I keep finding more evidence he's cheating.  Yesterday, while we were out he had some documents in the car.  Well, I happen to notice a name on the documents, and what appeared to be a fax number. Of course I do a reverse 411 to find out who the number belongs to, and they gave me the name of the young woman who's cell number has been appearing on my husband's cell phone at all hours of the day, and as I stare more at the fax, it appears the fax as sent at 4:32am.  So, no I start crumble, because at this point I realize that each time my spouse is in a hurry to get me of the phone its because he's in a hurry to get her on the phone.  And you know what he says to me about it.  He starts yelling, screaming carrying on about how I am bringing down our marriage, and trying to destroy him, and calls me a terrorist because I am checking his phone, and basically he keeps getting caught but he tells me there isn't  damn thing I'm going to do about it.   I don't know if it is my ego that hurts more, or my heart.  It is so painful to know that someone doesn't love you and there is absolutely nothing you can do to change it or do about it.  I have seen this happen to my mother, and now I have been cursed the very same way, I used criticize my mother for.  She has stayed with my father for over 40 years, and in those years my father has seeded 6 children outside of her marriage.  It was bad enough he had 3 prior to, 2 of whom were dropped off on my mother's door step within the first few months of their marriage.  But, I'll give her credit, she warned me not to date a guy with a child, and I didn't want to heed her warning because I thought he loved me, and nothing could impair that love.  LORD forgive me for being so very wrong.  I often have these impulses to call and find out the truth because I am tired of being yelled at , insulted, and I would rather ask the woman herself what the truth is, because believe it or not, more often than not the other woman will tell you the truth, 1. either because she didn't know 2. To have it out in the open to enable him to end the relationship with his spouse of significant other 3. Because she's been there and would rather be honest and end the painful saga of lies.  Either way, I never blame them unless they knew and had no respect for the marriage anyway.  Its weird.  I have never cheated on a boyfriend, never had a fling on the side, never collected phone numbers, and all my being honorable never got me anywhere.  I flashed my ring on so many occassions proudly to come home to an asshole who just ended a phone call with his ex girlfriend, or his current fling.  And I replay in my mind the moment I should have ended the relationship.  I knew from the very beginning he wasn't trust worthy.  I didn't follow it because I was so desperate to get out of the dysfunctional environment I was in, I figured he was the best I could do to get out of the situation.  He calls me paranoid and delusional, yet I keep stopping myself from calling these women to find out the truth because deep down I know the truth.  My everyday existence centers on the pain he inflicts on me, and never seems to end.  I have prayed, I have cried, and nothing makes it change.
