Poem Structure Question

I have found myself writing poems, or maybe technically prose, without any real background.

They are naturally coming out in the form of

Phrase A, Phrase B

Phrase C, Phrase D

Phrase E, Phrase F

Where the whole thing reads and ACE & BDF read. Is there a name for this sort of thing? How are they typically displayed on the page. Some are multiple stanzas making one page not enough as well.

Any help appreciated
