I am sad and very embarrassed to say I wrote much the same letter to my mother almost 18 years ago, but I was not getting married at the time.
I have re-acquainted myself with my disfellowshipped father and we have such an amazing relationship now. My mother on the other hand is still estranged.
My mother walked out on my siblings and myself when I was only 12 years old. The "Truth" justified my disowning of her. I have come to find that she is still not worthy of my, or my siblings love or really our respect. She is a bitter, angry and twisted individual.
But yet, I still feel such regret and dispair for ever writing such a letter to her during my "spiritual giant phase". I will never have a relationship with her not do I want one at this stage of my life but yet such a letter was so hurtful. that is something I will take to my grave with me and cannot undo.
I pity your son Inky. One day he will have to live with the same guilt but for him he will realize he caused suffering to someone that did nothing to deserve it.
I wish you well and wish I had the words to comfort you. On his behalf and since I doubt if I will get the opportunity to say it to my mother, I'm sorry.
