Why would the guy I was dating last year block me from his IG stories. We never followed each other nor have I watched stories. Why not just block me?

My profile is private and I never shared my handle with him, so for him to go our of his way to block just stories is a bit odd. Why not block me from your entire profile?

I figured if my number is still in his phone maybe that's how he found me by connecting his contacts buts that quite a few steps to block me from just stories.
