Should I be concerned, found e-mail on husbands computer that says to an old friend "girl" that he dated in high school over 10 years ago, he said "my marriage is not so peachy either, it would be easier if we chatted on yahoo messanger".... Keep in mind we were getting along very well and we never really had a fight until this. He told me he was probably mad at me on this day and was just reaching out to a friend. After 3 years marriage I have learned he is very sneaky and private on his computer, deletes histories and closes out windows when I walk in room.
