Way too much info, way too intrusive (H does not want to be in your memories and in your family forever), way too much everything. Quit trying to win him back, make the light bulb come on, etc. Stick to the basics.
Dear H,
I have decided to move as I believe it is the best thing for the boys and me to share a healthy and happy family life. This is a move for me and for my life with the boys, it is not meant to exclude you, their father, from the boys life. Let me know when you would like to discuss visitation.
I wish you happiness. I will quit acting as though you are accountable to me in your personal life. Your Rs with any OP are really your business at this point. I guess I get concerned about how our sons will take things in time, but that is my problem. It is really your job to manage your R with them, I recognize that it is inappropriate for me to try to do so.
Thank you for giving me the two greatest gifts of my life, S5 and S2.
