Is my ex recreating me through someone else?!

i was engaged to someone back in 2016 and I ended things because I was tired of his narcissistic tendencies, broken promises , controlling and stalking behavior, and verbal abuse. I moved on from him quickly and got married to my best friend two years after leaving my ex. I recently found out through a mutual friend he finally married someone else and made their wedding to be almost exactly what ex and I planned ours to be, right down to her wearing a dress extremely similar to the one I purchased for our wedding. Same colors, same bridal party attire, and his bride wore my necklace that he had gifted to me as a birthday present and I had given it back when we broke up. He gifted it to her as a wedding gift. She is oddly very similar looking to me and we even have similar interests. He even recreated our engagement pictures with the same color palette for their outfits. Is this weird to anyone else or is it just me?! I wish I could have warned her, or at least told her she’s wearing his ex fiancés birthday present that was worn on a daily basis on her wedding day. Yikes.
