Why did my ex delete his FB?

After NC, I sent him a touching message on FB apologizing for my actions. Then, he deactivated his account completely. Why didn't he block me?

I have never stalked him or tried to get in contact with him through his number/Skype because I thought it'd make him feel uncomfortable. If he told me he never wanted to speak to me ever again or block me, I will respect his wishes and never contact him again.

I dumped him by the way.
