Ex blocked me

My ex blocked me on social media after deleting me about a month ago. I have not spoken to them or had any contact whatsoever for months.

Why do u think they did this?

We ended on bad terms (their fault) and as much as I hate to admit it, i still love them, so the only reason I’m asking is because I still wanted them in my life in some way, even if only on social media, to see what they’re up to and how they’re doing.

I don’t know what reason they would have for blocking me if I have had no contact with them at all for months. What do you think?
