Boyfriend broke up with me because I fell asleep, any advice on what I should do moving forward?

I 25F have been dating a guy 27M and things have honestly been kind of up and down for a while. There were good moments, but communication was really inconsistent and sometimes things would escalate quickly. The day before yesterday, I fell asleep after work and missed his message. It just said he finished working out, then “ok goodnight.” I woke up around 11pm and called him right away on FaceTime. He answered but was cold and said I had woken him up and that he was tired, which I understood. I asked if he was mad, and he just kept saying “we’ll talk later.” I asked a few more times because the vibe felt really off, but he wouldn’t give a straight answer. Eventually I said “fine” and hung up.

The next day, I didn’t hear from him at all. After work around 5pm, I called to ask what was going on. He said he’d been having irrational thoughts and was wondering if I was cheating, since I had called late and was in the same clothes. He said he didn’t want to project those thoughts onto me, so he kept it in. I told him I wished he had said something earlier so I wasn’t left anxious all day, and he said I was making it about myself. Then he said “not to guilt trip you, but what if I was suicidal or something,” and started spiraling. He said “fuck it, you’re going to be mad at me anyway,” and asked if I was talking to someone else. I said no. He asked again, I said no again, and he responded with “it’s not like you’d tell me anyway.” He also said he didn’t bring it up sooner because he didn’t want it to turn into a fight. He mentioned how I shouldn’t have hung up on him like that, he said he understood why I felt frustrated with him but it doesn’t make it okay.

I apologized for falling asleep and told him I’d give him space until he was ready to talk. Later that evening, he messaged me about food, and I told him I was going to take a nap. He said “sleep well, I love you” and I told him I loved him back. I had taken melatonin and NyQuil and ended up sleeping through the night. While I was asleep, he tried to call and message me multiple times. When I woke up, the last texts were “Seriously?” and “Goodbye.” I also saw that I was blocked on Instagram. He’s blocked me on there before and once told me it’s a bad habit from past relationships.

I’ve reached out, explained everything, but this time I didn’t apologize and told him it’s his choice to end things by doing this but I at least deserve a conversation rather than abandonment. Now I just feel emotionally drained. It feels like I’m being blamed and shut out over things I didn’t even know were issues. I will be honest and say I blocked him for a few hours but was weak and unblocked and tried to call him multiple times.
Just wondering if anyone else has experienced something like this and how you handled it. Does this feel emotionally unhealthy or am I missing something? I’m kind of mentally spent
