What is the thought process of an ex blocking you back then the next day unblocking you while they’re still blocked?

Only noticed this because I had to go into our conversation to show someone something. He’s completely ignoring me in person after he received a warning to leave me alone but then unblocks me 🤣 if anything wouldn’t that make you want to keep me blocked even more?

I blocked him first because I am 100% done with him and he blocked back. He’s always blocked me and kept me blocked but these past couple times he unblocks hours later.

And don’t ask why I care, I’m allowed to care and want to know what causes this strange behaviour. He also shows a lot of borderline narcissistic traits.
