Boyfriend struggling with anger & depression

My boy is doing really well in his mental health recovery and we have helped each other heal in lots of ways. He used to have a serious anger and depression problem, but is medicated now (still figuring it out) and goes to therapy.

We haven't had a bad day in a while but today was bad. We practically live together and my roommate asked me to tell him to clean up his shit when I was in class and he lost it when I told him. He was so angry she didn't tell him herself and I was asking him why he was so angry and he hung up on me which he's never done before. Completely irrational.

I struggle also with lots of anxiety and depression and he ignored me the whoooole day which makes me incredibly anxious and upset, and he knows it. I called him like 8 times and he picked up twice, hanging up on me both times after little arguments.

I texted him a bunch of stuff saying that what hes feeling is irrational anger and he needs to see his therapist more than once a month because although they are rare, the bad days are so painful for me, worrying about him and being sad he ignores me. (He deals with anger by not talking to anyone the whole day).

I texted him to at least call and say goodnight because I can't sleep and he did but didn't feel better.

Did I handle this ok? I don't understand anger management issues at alllll and have no idea what to do. It's so upsetting to be ignored the whole day or deal with him being bitchy.

I never know where to validate his emotions and where to say they are irrational. I try and validate as much as possible but I'm scared he is going to think these emotions are healthy and normal :/
