I'm conflicted and I think I should end things?

My boyfriend of a few months has ADHD. I have been researching to get a better understanding and reading books/ articles about it. The first time he disappeared for a few day and I thought it was over. I texted him to find out if he was ok and he got back to me a few day saying that he had a depressive episode and he is so sorry. We continued our relationship, but this time around he ran out of Adderall and hasn't been able to cope. He went to another physician because his physician is out of town. The physician prescribed a different drug for him and he said it is making him become a mess. His body isn't able to adapt to the drug. He texts me he is super emotional and needs to self isolate for a few days. That was almost 3 weeks ago. I have been calling and texting him for weeks at this point and I'm getting no response at all. I was worried , but I know he is alive because he posted something on social media and he is liking reels. Its super hurtful and at this point I believe he is just ignoring me and being avoidant. I have completely backed off. If he didn't want to be with me he could simply tell me the truth and break up with me completely. I would understand, but this is unacceptable. The only way I can think of this working is if he gets cognitive behavioral therapy for ADHD, if not I am 100% out and he needs to switch back to Adderall. I wonder if he is too embarrassed to reach out because so much time has passed, but if that is the case I'm his girlfriend all he needs to do is just reach out. Can other people share there experience and advice. Thank you!
