Back Story to question: My mom asked me over the summer if my dad's girlfriend is going to be in the receiving line since they are not married, they have been together for 5 years, and my mom said my stepfather will be in the receiving line up. So last week I asked my dad how he felt and if he wanted his gf in the line and he said yes she will be standing next to him. So on Saturday I told my mom this and now she tells me that the receiving line up is us, our wedding party, then parents of the bride, then parents of the groom. To this she asked who is going to be standing first. My mom can be petty with things like that and I told my FI all this and he says they should stand where they want and figure it out amongst themselves. What is the right answer. Frankly I dont want to deal with the issues of deciding who goes first.
Side question: According to my mom's friend (who my mom goes to for all wedding questions) says the MOB is responsible for picking out what the mothers wear. I told her as long as they dont clash with the blue colors i picked I dont care what they wear. FI said to this that he does not see his mom wearing something my mom is making her wear.
How should I try to rein my mom in and get her to slow her roll. She made my head hurt thinking about seating assignments and I havent even sent out invites yet...or even ordered them O.O
