What to do about a controlling friend?

Me and my friend (let's call her Sue, Lmao) became friends about a year ago because we both needed a friendship after an ex-friend was only concerned about herself. However, I still felt I needed a lot more closer friends. so I had this idea of beach parties were I can invite other people from my school, and I could make more friends this year. The first person I told was Sue. II told Sue that she could come to the parties, of course. However, she began thinking she came up with the ideas of the parties. For example, she starting planning stuff for it, she will not take any of my ideas, and is basically pretending it was all her idea. I wouldn't mind if she was only doing this a few times, but she's calling me 24/7 about the parties. It's really getting to me because yesterday, I was with Sue and another friend (Linda), and I told Linda about the parties. I said that I had the idea of the parties and as soon as I said that, Sue cut me off and said "No! I did all the planning, you just had the start of the idea". Basically, she was saying that I barely had any part of it. I'm really sick of Sue trying to pretend it was all her idea. I've confronted her about how I feel, and she kind of ignored me. In fact, SHE sent out the invites to everyone. I know this may seem petty, but this is my idea and I am in need of more friends! Please tell me what I should do about this situation! Sorry about how long this is.
