I don't wanne be friends with her anymore

I have known this girl since childhood. We've been neighbors for 9 years and we would always play together. We didn't play that much but we saw each other often. In 2014 I moved from that neighborhood and from then I only saw her on our birthdays. In March 2019, we decided to meet again and from then we stayed in contact. In July 2019, we became super close. She came to a sleepover in my house and yes we had a great time but there were things that I didn't like about her. She was so noisy and annoying but back then it didn't bother me that much. From september to december 2019 we always hang out together and there I realised that I didn't consider her my friend. Every time I hung out with her I wished to be somewhere else and was so embarrassed by her. In January 2020, I had enough of her and blocked her on everything. She messaged me once but I ignored her. Then in February 2020, I thought about giving her one more chance because just blocking her like that wasn't good at all. I messaged and she was so happy. She immediately started calling me her best friend when I wasn't like how can I even be friends with someone I just reconsiled with. And now since quarantine we have always been talking but she annoys me so much and I want to tell her that I'm not her friend anymore but I don't know how. She always says how we would live together in the future and I agree with her because I don't want to hurt her feelings. Please help me!
