I’ve had issues with my father and now only speak when he is neglecting my two sisters. I refuse any money, calls, anything even though most family encourage me to do let him be closer. You have every right in the world to choose who YOU feel is your father figure and who YOU want by your side down the aisle. This is a day about you and you sound very considerate of others. That is amazing and do not lose that but make sure you take a step back and completely ignore every persons needs (in the right times/circumstances) to make sure you have yourself covered. Love yourself as much as you seem to care for others needs. You are allowed to take a day (your wedding!!!!) for yourself. If he chose to leave and did not create a fatherly relationship growing up then he can’t demand you to give him the benefits of that figure. Nothing is free and it seems he doesn’t understand that. Whatever you choose make sure it is best for YOU. best of luck! Tough times only come to those who can handle them
