I miss my best friend 😩

My best friend and I were friends for about 4/5 years. Unfortunately, about a year and a half ago, we stopped talking and I’m not even sure why. She was supposed to be a bridesmaid in my wedding, but was being really difficult about picking a dress. I wanted everyone to have on the same dress, but I was very open to what looked good on everyone and what everyone felt comfortable in. One day before one of our dress fittings, she told me that she might not be bale to make it, but that should would let me know. However, she didn’t show and never contacted me about it. One day following the dress fitting, she sent me something funny, I responded with emojis and that was the last we spoke. I miss her and her want to contact her, but idk if I should. She can be kind of petty. What should I do? 😩 I would love to have her around as I go through this life changing experience as she is already a mother. We literally talked about everything and anything and she was there for me during some of my lowest points.
