I went through this back when I was in separation. Twice, actually. The second time was almost worse because I knew exactly what was happening and it still gutted me when I thought I would be ready for it.
That moment where you realize you’ve been blocked is like getting kicked by a mule. Twice.
There could be a couple of reasons (I’ve heard of karmics actively taking runners phones and blocking the chaser) but it’s most probably soul shock. The connection between tfs gets so intense that the runner’s nervous system treats it like a threat, fight or flight kicks in hard, and they don’t have any framework for what they’re feeling because it doesn’t look like anything they’ve experienced in normal relationships.
Blocking is a “panic move”. Like a spiritual knee-jerk. If you actually talk to runners who came back from doing this, most of them can’t even articulate why they did it - it was survival instinct, not logic. I think somewhere on another thread there is an ex-runner who said exactly this.
You two were liking each other’s posts, there was closeness building, and then you were suddenly blocked. That pattern is so common it’s almost textbook. Sometimes the universe forces distance right at the point of closeness so you can both integrate whatever healing came through those interactions. Not saying that makes it hurt less.
I know you want answers. Of course you do.
But here’s what I can tell you from the other side of it (my twin blocked me for months the first time but the second time was shorter): your soul bond doesn’t break because someone hit a button on social media. The energetic connection keeps flowing regardless of distance. He came back. And when he did, growth had happened during separation on both sides.
