Why did my ex unblock me on whatsapp after 1.5 months?

Anonymous
He wanted to break up with me. Then he stalked me for about 2 months through whatsapp (i know this because i was stalking him too, he used to type and delete the messages but never send them to me) Then finally back in jan i messaged him saying hi. He read those messages and blocked me without replying. After that i got the point and tried to move on. Recently i was going through my whatsapp friends list. I saw him online (which means he unblocked me ). Why did he unblock me after a month and half? Whats the story now? Does that mean he moved on? or wants to reconnect?
