The word, 'date' is very unpoetic. You start to use it on almost every line near the end, and it begins to degrade the poem into weird choppy lines. It also nauseates me with silly high-school sappy-ness; I almost shudder when I hear the word. I would recommend swapping some of the 'date's out with synonyms like 'seeing each other', etc. Other than that, the poem is good.
