My parents are divorced and (no surprise) don't get along. My mom of course wants to be seated in the front row and my father will be walking me down the aisle. Where should I have him sit after? I thought they could behave just for me for a short ceremony but its becoming clear that they can't. I don't want to insult my dad by making him sit further back, but I also think it would be strange to seat him next to my mother in law. Am I over thinking this? Any advice?
