Blocking

My narc ex just blocked me last night. Two weeks ago, I initiated No Contact. He would not leave me alone and was begging me. I caved two days ago... I answered his text. Just to tell him goodbye again. Then he said I was cut off. So last night I sent him chocolates because I felt bad for telling him goodbye. Then I text him... he said leave me alone forever. I tried to apologize, he said text me one more time and you're blocked. I called and then he blocked me. I wanted to say something nasty to him but I couldn't. I feel like he may have unblocked me but I don't want to check.
