I'm having a power struggle with my sister - the MOH with planning my bridal shower. I'm very decisive and straightforward. Before it was a thing to plan, I had rough draft of the theme, food/games ideas, etc... I even listed cost-effective decorations, prizes, etc... It's pretty simple. Our parents have a beautiful garden in the backyard and I would want it there. I'm a "type A" person but very flexible. I hate being bossed around so I don't boss others around. I thought the rough draft would be easy for her and she would go off on that.
We're having a power struggle. It's all up to her but knowing my sister, she would insert something in there that she would want to do or something where she can own something. For example - years ago, the FH (then boyfriend) wanted to plan a surprise trip to Disneyland for my birthday. Being that she didn't want to be the third wheel, she convinced her friend to go on the trip. FH said he was surprised that she just invited her without saying anything but she claims that because she was able to because she was helping plan it. FH was a bit upset bc it was for my birthday. I was okay with it in the end but in hindsight, it still bothers me. She also brought her childhood best friend to my bachelorette weekend. I know her, I like her, she's invited to the wedding but it's not like we're best friends. She asked me if it was okay but it seemed like she already talked to her about it.
I tell her my cake flavor preference and she just tells me to not even plan it bc I'm not supposed to. Also - she tells all her friends that I need to just let her do all the work but I feel like she's just going to turn it into something that she wants and disregards my ideas - maybe add like 1 idea. Is this something we do together? Or just leave it up to her?
