Y'all I'm stressed out...I just called my fiancés mom and told her that we are rescheduling the wedding because of the 50% chance of thunderstorms all this week and next. And both the ceremony and reception are out door and she acted like she got mad???? We don't even have anything we need to make it happen this weekend? She been married 2 times and the second time she didn't have a wedding she just walked in the courthouse? So I guess she thinks I'm being picky. Well I only plan on being married once in my life and I have always dreamed of this day so I want it to be special. I don't want a huge fairy tale wedding I just want it to be pretty, simple, and ORGANIZED! Not a big mess. My dress don't even fit and she don't even care?? My wedding was suppose to be Saturday? That's in 3 days and gave me 2 days to take care of everything and I'm broke so wth????? I just don't see why she's being all rude and snappy. Yes her husband bought my dress an kyles tux and we're thankful but that's all we have and a wedding and reception takes more than that. It's not like we canceled we just changed the date. I just don't get it! But I honestly don't care anymore. I can't please everyone and Kyle understands so that's all that matters!
