i hear you OP, I’m also sad I’ve never been married and I’m a lot older than you.
When I was a teenager, I hated my surname and wanted to change it as soon as I reached 18. I didn’t, but told myself “I’m 18, in a couple of years I’ll be married so my surname will change then.”
In my 20s, I was desperate to get married, and thought that a woman getting married for the first time in her 30s was a bit sad. (Don’t worry, I get my comeuppance later in the story).
Then when I reached my 30s, still not married, I thought I absolutely “had” to get married soon, as a woman getting married for the first time in her 40s was tragic.
Repeat for each decade. I’m now 51, not married, never been engaged, never been proposed to. It makes me sad. It’s not about “the wedding” ( although I would like to wear a pretty frock ) it’s about wanting someone to love me enough that they want to marry me.
And I’m STILL stuck with the surname I hated as a teen! Should have changed it by deed poll when I was 18.
