Write something only the two of you would understand. The strongest romantic wishes reference an inside thing — the way they make coffee, an old fight that became a joke, the small daily yes — instead of generic 'forever and always' language. The 30 examples on this page sit in that register; lift one and replace a phrase with the actual specific.
Either works, but the wrong length is always obvious. A two-sentence text needs to be one strong observation, no padding. A full card needs three short paragraphs at most — opening warmth, a specific memory or hope, a closing line that promises something small and true. The wishes on this page are sized for both.
That's the entire point. Most wishes here are written generically so you can drop in the specific that turns it into yours — the name, the year you started, the memory you both still bring up. Our AI generator can also rewrite a wish around the personal details you give it.
