Annoying him

So I was talking to my bf and asked him if he wanted to FaceTime. I was tired annoyed and just wanted to tell him good night over the phone instead of through text. I texted him first but it had been a while since I texted so I thought either he is sleep or busy so I called one time it went straight to FaceTime failed so I told him gn I love you. Then he says call him. So I call him. And I get ignored for about 30 minutes and then ask him why he is ignoring me. I knew he was watching a movie and the last time I tried to talk to him while he was busy he got an attitude with me saying that I called him while he was busy so he was going to ignore me this time a whole hour because I called him back and he was no longer available to talk. This is honestly disgusting me very much and making me very angry. Because I'm sure he doesn't do his friends that way and would be really upset if I did that to him. So he hangs up in my face and I ask him can we talk about it because I'm literally scared to call him almost period now because how crazy he is about it and he just says okay for every answer when I ask him why he keeps doing that he says because it's annoying (for me to ask the question because I am having an issue). Of course I'm sure if it was him we could talk about it. I am also even more afraid to talk about it because he keeps bringing up how we haven't had a big fight in a long time and I don't want to be the one at fault because even if it wasn't my fault I would still be at fault regardless. So in all honesty what should I do?
