Dear LIB readers: I went through my husband's phone and now I'm devastated

From a female LIB reader

I went through my husband's phone yesterday because of my recent suspicions that he's cheating on me but what I saw on the phone was far worse than what I was expecting to find there. It has practically ruined my life. My husband told his cousin via bb chat that he had fallen out of love with me a long time ago, that the only reason he's still in the marriage was because of our three kids. We've been married for eight years and I've done everything I know how to be a good wife and this is what I get? It would have been less painful if he was cheating. I don't know what to do. I even called in sick to work this morning because I've not been able to stop crying. Should I confront him? Should I release him by giving him a divorce? I love this man to death and I can't believe he stopped loving me along the way. What did I do? He always said I was a good wife, when did I stop being that? He has been so distant lately that I thought he was seeing another woman. My husband has ruined my life.
