A short, but sweet poem that is appropriate for a 10-month anniversary is: "To explain how much I love you, I don’t know where to start. To understand the intensity, you’ll have to dive in my heart. Endlessly vast and larger than life, it will forever be. Just like the distance to the stars and the depth of the seas. Happy anniversary."
A more casual, fun poem for a 10-month anniversary is: "Other couples should learn a thing or two, about how to be a couple from me and you. Happy anniversary!" You can also use: "Our anniversary is not a mere date for me. It a reminder that you and I are meant to be."
If you can't find a poem that adequately expresses how you feel about your partner, consider writing your own. Start by taking a famous love poem and modifying it, by adding your own thoughts. For instance, use one of Shakespeare's sonnets, but customize it by adding character traits you appreciate about your partner.
When you're writing an anniversary poem, remember that specific is best. Instead of simply writing, "You are beautiful," personalize the poem by adding the facts that you love your partner's deep blue eyes and sparkling smile. Writing from the heart creates an unforgettable gift.
