AITA for not letting my brother and his fiance use my house for their wedding, after they threw me and my family out of their new home.

I(28F) recently bought my dream home, and my brother(27M) and his fiance saw it and thought it was perfect for their wedding venue. <br><br>I said no, but they convinced me. Then I started to get calls from vendors my brother and his fiance chose, asking where they could deliver the wedding arch, tables, chairs, and other equipment. I said they could put them in my backyard. They said they wanted to put it in my living room, kitchen, and dining room. <br><br>I said no, and my brother called me asking what the hell was wrong with me. I told him I wasn’t going to let them furnish my house like it was their personal wedding hall. He said I was selfish, and I was messing up his wedding. So I said they couldn’t use my house anymore. <br><br>He called me screaming that I was a bitch and an asshole. I hung up, and then my parents called me, asking what was wrong with me. I told them what happened, and they said I should have just let them do whatever they want. I said no, and then they started yelling that I was an asshole. <br><br><br>Meanwhile, my brother and his fiance just bought a house, and he asked our family to get out because he wanted to spend time alone with his fiance. None of us have seen the house, even after helping them with their down payment.
