Is It Rude To Not Invite Someone If You Were In Their Wedding?

So, I’m 21 years old and I graduated high school in 2016. I grew up and went to school with this girl, so i’ve known her for my entire life. Growing up she was kind of my friend but also very rude to me. I was still nice to her and talked to her in high school because we went to a small school but after we graduated I completely stopped talking to her as her and I don’t really have anything in common. In 2017 she asked me to be a bridesmaid in her wedding. She was marrying a guy she dated when her and I were 14 and still friends, him and I never got along and since her and I didn’t speak for a couple years, I was hesitant to be in her wedding. Her family and mine are very close so my mom told me for the sake of HER friendships with her parents that i should. She doesn’t have a lot of friends so i knew I was her last option for a bridal party. She wasn’t the best to deal with and pretty much left me in the dark and made me pay for everything, which I was okay with since it was a small and quick wedding. I went and her and I literally have not spoken since. Now that i’m engaged I’m wondering if i should invite her. I’m from Ohio and my FH is from California so we moved out here summer of 2018. We plan on having the wedding here since this is our home, which means all of my guests have to travel. I wanted to keep my guest list medium or small since it’s a lot to ask of people and a lot of stress on me for planning when i’m not sure who can come or not. Also because i’m young im not established in any career (part time only jobs because school) and i’m pretty broke so i’m trying to keep my wedding non expensive but nice, and wedding venues out here are pretty high in price plus the cost per guest. lol. Is it rude to not invite her even though I was in her wedding, or should I still invite her + her husband to be polite?
