I know I am overreacting but I need to get this off my chest and get some sound advice.
My FI and I got engaged a few months ago and it will me our first wedding. My cousin, who is in her mid 30's and just recently got divorced, offered to help me plan which I thought was great because she is super organized and having been married kind of knows what needs to be done for a wedding. That lasted all of maybe a week until she announced her engagement. Don't get me wrong I was very excited for her and her FI who is wonderful. What irritated me is that it happened so soon after our engagement but I was aware I was acting like a child. I was feeling fine about the whole thing until she started pressing for details such as dates and themes and what not. I told her the basics the date we wanted and our theme only to have her tell me they were thinking of a date very close to ours, like same week, and that she wanted the same theme, yes I know I don't have my theme trademarked or anything. So my FI and I decided that we really liked our date so we just decided to move the wedding back a year, which will help with finances since I'm just finishing school. Now I come to find out that she didn't pick the date that she had been insistant on and instead chose the date of our grandmother's birthday. I think this is a cool way to honor her, but after she threw a fit about that other date? Now I did create a Pintrest board with wedding ideas but at the time she did not use Pintrest. She started soon after her engagement and promptly started following my board and repined everything directly onto her board. What really bugs me is that this is the second marriage for both her and her FI and they are making a huge production out of it. She even sent me a text accidentally that was supposed to go to her FI's daughter saying "well your dad says i can have whatever I want for my day," am I crazy or does that seem snarky and inappropriate to send to your FI's daughter? The worst part is that ever since she got engaged she has been ignoring me when we have family functions and whispering behind my back. I almost want to completely change my theme just to avoid drama. At this point I just want these weddings over so that everything can go back to normal for us because we used to be very very close.
Like I said I know this is crazy but I needed to vent and could always use suggestions for how to not let these things bother me, to keep our relationship intact, and whatever else you got
Thank you!
