TweetHi. You sound like you are worried about things that might not even happen. After you get engaged, sit down with everyone separately and ask them if they are going to contribute any money for the wedding. They might also offer to pay for specific things (ex-flowers). But you gave everyone the chance to help pay, even ask your mom, maybe she'd like to make little take home gifts at the table. Even if people make things for you everything will help. Plus they feel like they have really contributed to your day.
I dont agree that it's the brides parents 100%, because most of the weddings I've gone to everyone has paid for it even the couple.
My parents paid for about 98% of my own wedding. My husbands parents didn't offer any extra money which made me feel like they were being really cheap. My parents paid about $22,000 and they paid an extra $3000. It's like thanks but no thanks! It still bothers me to this day. If I ever have a son I want to really give him a lot so I don't get looked at this way.
Weddings are a pain, but it's a wonderful memory, you only get 2 big parties in life--your wedding and your funeral... if you don't have a big wedding you will miss out on both!
