Blew up his phone

I’m in a LDR with a guy, met him 3 months ago in another city. He initiated everything to begin with.
Today I had a really low point when I basically created a problem out of nothing while texting him, started texting a lot and deleting. He respectfully backed off and explained that he didn’t want to hurt me and thought we need to have some silence. I just couldn’t stop myself…
He then texted at night if I was okay, asked if I was drunk (which I wasn’t), said that I was obsessive and it wasn’t healthy, wished me good night.
I know I ****ed up.
We had an argument two months ago where he went silent for a week and I thought it was over. I think today I was being anxious and fixated when I realised we were arguing. I can’t explain it. It’s like I wasn’t being myself. I wanted to makeup, texted then thought it wasn’t good enough, then deleted etc etc.
I replied to his texts saying that I’m embarrassed, I’m sorry. My behaviour wasn’t okay and wasn’t healthy. He needs peace, space boundaries. He didn’t deserve this. I said I’d never text and delete again, regardless of whether I hear from him or not.
So, he hasn’t read it yet.
I think I’ll just stay silent if he doesn’t respond. If he does, I might send a greeting polite text, and stay quiet. I’m so embarrassed and ashamed. He must think I’m mental. I’d absolutely hate it if someone did this to me.
I’m off the pill for a month. Don’t know if it’s hormones or just the anxiety to do the wrong thing…. I don’t see how I can recover from this with him
