Please help

So my boyfriend and i have been together for a year, i love him a lot but whenever we’re mad at each other we dont talk, we’re both stubborn and dont want to make the first move. We even went two days without talking. I brought him a chain for our anniversary which was tuesday and he lost it already. So i was taking a nap and he called me and said he lost it so i said okay, he said what do you mean okay and i just said okay. (He pissed me off earlier so i was being nonchalant) So he was like alright and hung up. So i woke up, text him and asked how did he lose it and he said why , you didnt care earlier when i told you. So he didnt text me back and i called him and tried to be civil and asked how he lost it and where, he had an attitude so i just hung up and we haven’t talked since then, that was at 5. I know we’re gonna fall right back into that cycle of being stubborn and not texting each other. I want to change that but it also takes two people. I think we just have bad communication. Any advice would be great.
