If you have a feeling that someone might cause a problem for you during your planning or on the day I suggust not having them in your wedding party. I had two of my best friends from College be my maid of honors, one did an amazing job and I love her to death she was my second MOH but wish she were my first. My first MOH was self obsorbed during my whole wedding planning and would never let me talk about myself or the wedding and would only ever talk about the guys she is dating. I should have realized what type of person she is before becuase we always say "well that is just how she is" but on my wedding its the one day where it can be about me.
According to her this is wrong because at my own wedding she was talking about me behind my back to a friend from highschool. Saying I was self involved, even if i was your wedding day is a day you can be. She was lake to my shower, thirty minutes lake to rehersal and then got drunk at dinner. At the wedding her bf came and she hung on to him the whole time and went and madeout with him outside ( i heard later) I have heard a lot of friendships end after weddings and I believe that this is one friendship that is going to end for me. Why have a friend that is only into what they are doing and not abotu other people if they wont do the same as you would do for them, its not worth it. Just letting all the future brides be aware of who you are trusting to be there for you on your big day, because it is YOUR DAY!
