Have not heard from boyfriend in over 24 hours?

Here are some important information to know... my boyfriend (34M) and I (29F) have been in a relationship for almost 2 years now... we currently don't live together but see each other a few days each week and something that is very unique to our relationship is that when apart, we have not gone a single day without communicating with each other since the 1st day of our relationship. It is a streak that is extremely special to us and we have always placed a lot of value on "not breaking the streak" and making sure we communicate in some way every single day. In the past, my boyfriend and I have gotten into bad arguments where we would not text or call each other for most of the day but before we hit 24 hours of not talking, we always make sure to at least say something so the daily streak of communication isn't broken. There are some things that have happened during our relationship that my boyfriend has not been able to heal from so he will bring it up from time to time and spiral into overthinking, anxiousness, etc. Two days ago, my boyfriend randomly thought about something I did that hurt him in the past and completely spiraled out of control. He accused me of so many false things and started an argument for no reason (we were completely fine earlier that day and nothing triggered it). I tried to calm him down and asked him to stop but he would not stop sending me text after text of his anxious thoughts and verbally abusing me. I told him that if he would not stop, I would have to turn my phone off since I did not deserve that treatment from him. I ended up turning my phone off. Since yesterday, over 24 hours ago, I have not heard from him today. Our streak has been broken, after almost two years of talking daily. I'm unsure of what to think. I did nothing to trigger his emotional spiral and verbal abuse. It is also very unlike him to go completely silent on me... Do I consider us broken up?
