Family drama long rant so sorry but need to let it out

I don’t know if I’m in the wrong or my sister just being dramatic and wants the whole year to herself. My fiancé and I have been together for 19 yrs. My sister and hers have been together for 2. My sisters fiancé, not even my sister, asked me what year I was planning I said 2023. Nothing was said about them planning or even looking at venues. I heard from my parents probably 3 weeks later that they were looking at venues so I decided why not start looking. I have a friend getting married as well and she was telling me about her plans and dress so that made me excited and I jumped the gun Even more. I found a venue and told my sister I was thinking about sept 17. I eventually told her I booked sept 17th 2022. She found one to and decided to do august 27th 2022. I wasn’t bothered. Now when it comes to planning, Theres a big difference. She’s going all out for her wedding. 200 people, it’s black tie and she has no budget so she’s wanting to hire the best of the best. She wants a bridal shower and a bachelorette. This is her second marriage. Her first marriage she didn’t even tell us she was doing it and just did a jp in her house with his family only. I’m more simple and much quieter then my sister. And on a budget. I have probably 70 people and I’m planning it all on my own and I’m getting things like photography and the cake as gifts from friends and family. Oh and my mil are doing all my flowers and I found bridesmaids dresses online. I have a venue but it’s nothing over the top. I don’t want a bridal shower or a bachelorette. Just simple. I want to Finally Get married and have a party. Do you think it’s an issue how I said I was doing 2023 then decided on 2022? They claimed they were working around me which I get but I’m not seeing an issue with this because I’m not having the traditional wedding. Nothing is interfering because I’m not wanting all that stuff. I spoke with my family about the weddings and no one was complaining. What are your thoughts
