Guys, did my ex unfollow me out of jealousy?

My ex and I had been following each other on Spotify for months after breaking up. He had even been in another relationship with another girl and even though we were no longer in contact I noticed that we still followed each other. He had even saved a song I had sent him 'what you won't do for love' and still had it in one of his playlists last time I checked. He had also another song that had many references to me that were way too specific. Christmas 2023 came and we were still following each other FAST forward to February 2024 and he unfollowed me. In December of 2023 I started following my cousin and his profile pic is him taking a selfie. And I have just realized my ex has unfollowed me. So my question is, is it possible my ex thought I had moved on (thinking I'm with my cousin) and unfollowed me? We hadn't been together for months and yet still followed each other but now that my cousin follows me, he unfollows?
