Ok, so the groom's parents divorced over 10 years ago, but things are still weird/awkward. His mom is bitter about his dad's new wife, is definitely a squeaky wheel, and is bringing a date. How do I seat them at the ceremony? I know obviously they'll have the front row, but I can see them already fighting about who gets to be closer to the center aisle. They'll both be bringing their respective significant others. Should it go (starting from the center aisle) his mom (the squeaky wheel), her date, his dad, his wife? We have never met his mom's date, but are really happy she is seeing someone, but it seems odd to put mom's date in a better position than his dad's wife, whom we've known for years. Am I way overthinking this? Could I put the two sets right close to the center aisle, but one behind the other? (can only imagine the fireworks that might cause). Are there rules? Please say there are rules, and they are established!
