A year ago, my fiance and I got engaged. We had planned to get married in 2015, but financial insentives convinced us to tie the knot early in a very small ceremony (just us and parents) and have a "wedding" in 2015. This decision was made in early October with the mini-wedding to be in January. We have had a very rocky relationship with one of my fiance's sisters for several years now. She is hypocritical, a habitual liar and a drama queen. Two weeks after we talked to his family about the change in plans, she announced she was engaged to her boyfriend of two weeks whom nobody in her family had met and that the wedding was going to be on December 22. There are many people in my life that if they had made this announcement I would be excited for, but her history assures me that this is a combination of insecurity about the fact that her younger brother is getting married first and an attempt to upstage our wedding. Not long after we got engaged she declared that she was as well with a guy she had been dating for a month (this is a different guy then the one she is now marrying). She showed up at our engagement party claiming she had been punched the night before and had a broken nose (no bruises or anything), then halfway through the party she informed eveyone she was moving to Ireland. The entire time that I have known her, if the event is about someone else she will make it about her. If she can't make it about her then she will attempt to upstage the whole event. I have been trying hard to just move on but I am unbelieveably hurt and furious. Every time I hear about it it just upsets me all over again. I don't think I'm being a Bridezilla about this. My fiance's mom and other sister not only were pissed as well but called after her announcement to see if we were ok. I'm just so upset because I feel like she is stealing a time that is supposed to be about my fiance and I and getting away with it.
