Weird blocking situation?

Hi everyone, I stopped talking to a guy about a month ago—things were left pretty vague, and since we live far apart, I wasn’t sure if anything long-term would work. During the time we weren’t speaking, I noticed he followed a girl recently, but there’s no clear sign they’re dating—just that he followed her. Then out of nowhere, she messaged me, deleted it straight away, and blocked me on all my accounts, including ones he still follows and my business account too that’s for my work. I’ve never interacted with her, so it felt really random. A week or two after that, he messaged me saying he misses me, thinks about me all the time, and wishes he could spend his birthday with me—while I’m still blocked by her for no reason. I didn’t respond, but I’m genuinely confused—does anyone know what might be going on here? Why is she even blocking me in the first place?
