<human>: Can you give me the gist of the text in a nutshell?

After 3 weeks of NC, I texted my ex yesterday letting her know I hoped her classes were going okay, and asked her if she wanted to grab coffee or a drink sometime, but no rush. 24 hours later, I hadn't heard from her, so I texted her again saying I was sorry, I shouldn't have reached out, that it was probably too soon, and I wasn't ready.

Several hours later, I discover that I had blocked her one night after a few drinks on my iPhone. It was sort of a way for me to make her not calling me my decision. Illogical? Slightly. Which means that, although I could send her texts, I could not receive texts from her. I couldn't tell whether she had responded and still can't.

So now, I'm stuck. Before I go back into NC, which is probably inevitable. I don't know whether I should try to explain myself. Thoughts if I want to salvage the possibility of getting back together at some point?
<bot>: Should I explain to my ex-GF that I didn't get any potential reply texts because I'd blocked her number?
