Until you come to terms with the "fairy tale" illusion - ... you are not ready to date.
If you did have a fairy tale -- it would not have ended. You had a NORMAL marriage and relationship. Good times, bad times, shiny spots and mud pits. You were young and joyful and naive. That is what creates a fairy tale ideal.
You need to accept that your marriage is over, and has been for a long time. That you had good times but it was NEVER perfect. That you created a myth, and you are trying to embrace it still.
As to different interests -- are you looking for a clone or someone interesting?
-------------------- Today you are You, that is truer than true. There is no one alive who is Youer than You.
