Let me preface this with saying I in no way expect my wedding to be the center of anyone's world. I have been in the middle of wedding planning since last October and quickly learned the fact that no one is going to care about your wedding in the same way you do, and I have made peace with that I understand especially in these times that it is not on the top of really anyone's worry list.
So, I have two other siblings both of them being gay (this matters to the story) we grew up in a very southern baptist household, however it was just my Dad raising us with my mom having left us. Anyways, my sister is older and she stepped into the mother role (unhealthy I know) and pretty much helped raise me. With me being the baby once the older two siblings were out of the house there were a lot of things I got that they didn't get. My Dad having a better job and only having to take care of one kid versus 3 is the reason, but that never really cause issues with my siblings and I. My brother always knew he was gay, and we all did too, when he came out my dad was accepting of it and nothing changed his love for my brother. Now with my sister she was always hiding relationships with girls and lied to us a lot I won't get into all of that but it really hurt both my Dad and myself. It really changed her and my Dad's relationship and not because she is gay but because there was a lot of broken trust there with some really big stuff. She ended up getting engaged to someone whom she hid the relationship from us and at the time of their engagement we as a family were still trying to get to know this person she had been with for a long time, but hid from us mind you we already knew she was gay and again no judgement from my dad or myself. When they got married and were planning the wedding she really kept my Dad out of the loop with a lot of stuff, and of course there were a few family members that refused to come because it being a same sex wedding (I don't agree with them not coming) so my sister ended up getting really hurt. My Dad walked her down the aisle, gave her away, they had an emotional first dance everything that happens at a wedding.
Flash forward to my wedding now, I have asked her to be my matron of honor. I have been getting very hurt by her because she has been struggling with jealous that my Dad is helping way more with my wedding than he did hers, she has admitted these jealous feelings to me. Now mind you, I have talked to my Dad about this and he says the only reason he is helping more with mine is because I am involving him more, my fiance has actually made an effort with him, etc it has nothing to do with her having had a same sex wedding which is the truth. So here I am really hurt because she is not keeping her feelings in check and has been blatantly rude to me in front of people, at my own bridal shower she threw for me I ended up getting really upset and my guests were all asking me why was she being so rude. I have asked her if I did anything wrong, being a bridezilla, rude, etc and she says no not at all. Sorry for the long post I am just in a really tough position I don't know what to do. We have talked about this issue a lot, I have listened to her worries and hurt and been there for her. I am worried that her sour attitude is going to be there at future events and at the wedding. I know her feelings are her responsibility but she has a big role in this wedding and everything to do with it. Plus she's my sister and we have never experienced this with each other. WWhat should I do?
