More problems than I thought

I have just recently found out that my wonderful husband has been cheating on me. I have so many emotions I do not know where to begin. I don't really know what hurts more that he did it or that o discovered it. I am made he dis not have the balls to tell me himself and all he could say to me is he was in love with her and wanted a divorce. I have loved him my whole life it seems like. Now I do nor know how to stop loving him. I have agreed to the divorce, but feel cheated out of an explanation. I feel I have lost my best friend and confidant.
