I'm really bothered that I had to do this, but I just kicked a good friend out of my wedding party. She's always been flaky - constantly cancelling plans at the last minute and stuff - but I really wanted her to stand up for me so I asked her as soon as my family knew about the engagement which was 9 months ago.This past Thursday I got a call from White House Black Market about a dress and was told that I could get a group discount if the dresses were ordered by this coming Tuesday. I set up an appointment with them for 10am today and apologized to my BM's for the last minute noticed. She responded saying that it was no problem and that she was so excited to get the dress. Then, last night, see texts me and says that she can't afford the dress. I totally understand that money is tight for her - she's a new teacher and is looking for a job right now - but it's not like I dropped this on her a few days ago. She's known for 9 months that she was going to need to buy a dress and I told my girls 3 months ago (when she was still getting a regular paycheck) that we would be ordering in September.If I knew that I would be reimbursed for the dress I would have no problem buying it for her but since this is the millionth and one time she done something like this I just can't bring myself to do it. Especially since she couldn't be truthful about her situation in the first place. I'm really hurt by this and have never been more angry. I've always been the person that defends her when she cancels at the last minute and I feel like if she was a true friend she would do whatever it takes to be there for me. After much thought I decided to let her go from the WP because I feel like I just can't depend on her. If she can't be honest with me or follow through with plans that were made how can I know that she would even show up for the wedding?When I told her this she was very gracious and said she completely understood and that I had every right to be angry. She even thanked me for everything I've done for her (she was in a car accident years ago that killed her then best friend and it's been, understandably, hard for her) and said that she hopes we can continue to be friends, even if it's not right away.I feel like I made the right decision but I also feel horrible about it.I just needed to get it off my chest so thanks for reading. Mean replies aren't necessary, I feel bad enough about this as it is.
