So my parents are divorced, and while my dad tries very hard to be mature and civil, my mother is kind of insane. What suggestions does anyone have to keep them apart as much as possible to avoid any possible wedding day drama. I have told my dad I would want at least one picture of them two together with me, and he said that is okay. I have not talked to my mom about this yet. I am going to sit my dad with my FH's family during the reception. There's just so much... the rehearsal, the rehearsal dinner, where to seat them during the ceremony (I will NOT sit my father anywhere other than the front row because of my mother's pettiness!). Any suggestions?
