Why he blocked my ig business account 2 months after the breakup? He is with someone else (i think)

Classic question. I have 4 IG

1. Primary account (private)
2. Spam acc (private)
3. My food blog (open)
4. My business account (open)

At the beginning of our breakup, he blocked no 1,2,3. He followed no 4 still. But because i feel uneasy, i removed him 1 week post break up, because my business has not yet take off at that time and I dont want him to see my progress, i feel pressured.

I still type his account almost everyday, but i kinda gave up because i am disappointed with many incoming information about him with another girl. His profile also private.

I am not hoping for things, i know its over

But after sometime, last week i realize he unblock my IG no 2 but we both don’t reach out. Just quiet.

Now my business has launched for the past 3 weeks. I realized yesterday that he blocked my business account.

Just wondering why? I unfollowed his business account, but i dont block. I thought it should be a neutral page. Just wondering why if anyone has their opinion, would like to hear it.
