Is this stonewalling?

Any time that my boyfriend gets upset with me when we’re apart (we live together), he cuts all communication. He’ll either simply stop responding, shut his phone off, or once in a while will actually block me. He also stops sharing his location too. Sometimes it lasts for minutes, sometimes hours, one time it was almost a whole week. I try to call or text him because I just get really sad and confused but he ignores it. Then when he comes back, he tells me that it annoys him how I “blow his phone up” and how he “just does it so he doesn’t say anything mean while he’s mad”. He doesn’t even acknowledge that any communication I send him while he is ignoring me is me saying that I miss him. And maybe if you didn’t just run off and leave me with nothing I wouldn’t be so hurt and wouldn’t try to reach you. And I don’t see why it’s so hard to say “hey we’re okay but I just need some space, I still love you and I will see you later”. I feel like the way he’s doing it is like his way of punishing me or something.

He’s also doing this right now. He’s logged out of his Facebook and blocked my number. Which is really cool considering the fact I’m 38 weeks pregnant 😒🤬
