Oh boy, oh boy, I know this all too well
I live in Scotland, after living here for a while, met my BF here, I proposed to him, decided to have the wedding here, as this is our home and this is where we want it.
99% of my family and friends think getting married in Scotland is the best idea ever and are saving their pennies to get here for it. My parents are beyond excited, in fact once we started hemming and hawing about wedding planning they said, "Make sure you get married in Scotland!" My older sister has been dragging her feet and causing a big fuss- I posted about it in the IA thread and lots of people have been in the same situation. My thoughts are though, its our wedding to celebrate, I want no pressure for anyone to make it or not. If they can, awesome. If not, that's ok, I completely, 100% understand. We're having a party back in the states for those who can't/won't make it here. All is well though- its about celebrating our love and if we need to celebrate it twice, three times, 8 times, who cares, all good fun!!!
No matter where you choose, someone is going to kick up a fuss. Its not easy. Especially as so many parents feel that a wedding is the next thing in their lives, they look forward to it as much as we do. You do have to remember your mom is probably dealing with lots of emotions for the move, as well as not being able to have "the wedding of her dreams for you" so its a bit tough. All you can try and do is try and ease her fears the best way- pay for tickets, have 2 weddings, do whatever you can do, within your budget, and time and will to do, to ease it for her.
Hang in there
