sorry to hear your news. Similar to RonH, my wife abandoned our children (two sons) while I was in the Gulf playing soldier. Suddenly I was a civilian and single Dad. It took awhile, but life goes on. Because of the boys, it gets funner every day. The boys and my bikes helped me hold it together until I got squared away. Took awhile to learn it wasn't me. Took awhile to learn that life is still good. Like others have said.... Get out and ride (often.) Find something to laugh about (real belly laughing... almost pee your pants laughing) every day. Smile lots. Know that you have friends.
and....
be well,
jim
