This looks like and example of Haiku poetry.
Even though in the West, the 5-7-5 pattern of syllables is more strictly observed, even masters of the form do not always adhere to this exact restriction.
It could also be considered a Haiku with a nod to Common English Hymn Metres which follow an 8-6-8-6 syllable rhythm.
As for the repetition; though it is uncommon in Haiku, there are some that welcome the technique into the tradition.
Notice the syllables:
6 - So, are you missing me?
8 - Missing me so much that you crave,
6 - crave to meet me right now...
An example of 5-7-5 Haiku:
5 - Whitecaps on the bay:
7 - A broken signboard banging
5 - In the April wind.
~ Richard Wright (collected in Haiku: This Other World, Arcade Publishing, 1998)
