Advice Please: Missing the solo life

Hi everyone. So yesterday my husband and I had a chat about why I want to spend my birthday alone. Lately he gets quickly frustrated and I just don't want that possibility of the energy on my birthday. Last year he hijacked my birthday trip to New York because he didn't want to go to some places I wanted to go to. basically we don't have a lot of the same interest but that doesn't bother me. The thing is he is sad I want to be alone. He said it seems like a red flag for me to want to be alone on my birthday. But I never lived alone. I went from living with my parents to living with him after getting married. I've been feeling the need to be alone since 5 months after being married. IDK can anyone help my diagnose how I'm feeling and how to deal with it. I just feel lost. I feel like I'm ruining my marriage. Anyone ever felt that way the first couples months of marriage or late in their marriage?
