Getting married this may and no maid of honor please read♥️

My sister was my maid of honor but we got into a huge fight and she dropped out of my wedding… is it ok that I don’t have one? I don’t know anyone else… I just don’t know what to do and no I don’t want her back in my wedding if she’s going to disrespect me and my fiancé. Looking for advice no judgment. I have 6 bridesmaids and 7 groomsmen it’s a small wedding outdoors… I just wanted everything to be beautiful now I have one guy walks down by himself but that’s ok ❤️
