Getting mad easily

Does anyone else’s boyfriend go from “I love you so much I wanna marry you” to not talking to you bc of something so minute? Like tonight he’s on his way home and wanted to get pizza and I wanted to go so I said yes let’s go! Then I remembered I had bought pizza earlier so we could save money and stay home and now he’s mad at me? I love him so much and I really do feel loved but his moods change so fast over small things.
