The speaker is looking back on a painful loss. Someone they loved was drawn to another girl, named Kyleigh, and the speaker didn't realize it was happening until it was done. The poem opens with her name in quotation marks, as if it still stings to say, or as if the name has stuck in the speaker's mind and won't leave.
What stands out is how the speaker feels about it. There's no loud anger here. Instead, there's a quiet, lasting hurt: the speaker says that thinking about how Kyleigh loved this person "as i did" still brings tears "to this day." That suggests the wound hasn't healed. The comparison to an orphan is the emotional center. It makes the loss sound like losing a family, being left without anyone to turn to.
The short lines and lowercase style give the poem a hushed, exposed mood. It feels like a confession, sad and lonely, with the speaker still stuck in the memory.
