So this is a two parter with a little background first. My parents are both alive, close to me & married to each other. My fiancé's mother passed away 4 yrs ago & his father has since remarried. His Dad is wonderful & funny but his stepmother is a little pushy. She didn't raise any of the kids, everyone was married & on their own by the time she came into the picture. They live about 1200 miles away. My fiancé & I had set a date for April of 2016 in order to have time to pay for most of the wedding ourselves & for me to have time to lose weight after our baby is born in January. This is a second wedding for both of us, I eloped the first time & didn't have a traditional wedding with the dress, father/daughter dance & reception with family & friends. I really want one this time & my fiancé agrees. My fiancé's dad & a brother will be busy with work at that time. His stepmother asked us to reschedule our wedding after talking to the rest of my fiancé's family first. They are a different religion so they don't understand that this isn't just a cake & punch kind of reception that can be easily changed & multiple vendors to be coordinated with a change. I really want the whole family there for my fiancé's sake but the way she approached it has just set me on edge. Especially since there was a decision made then we were expected to agree without our input.
So my questions are:
1) Since she is not his mother & did not raise him or his siblings how much of a part should she take in the wedding? Should she escorted like my mother will or should she be already sitting with the other guests? Should she be in the reception line? I am planning on having an elaborate bouquet to memorialize his mother he was very close to at the wedding & reception with a card saying in memory of. My fiancé liked the idea a lot.
2) Is she listed on our invitations or announcement? I've read that we should put "son of ---- and the late ----- -----" but where does stepmom fit?
I know this sounds long winded but I really need advice on how to set boundaries with her involvement I can see her butting heads with my mom quickly if she continues to dictate my wedding.
