Gwyn's "eclipse" starts out sounding like a science lesson, with the sun, moon, stars and earth moving in perfect harmony. Then it turns personal. The speaker uses the idea of an eclipse, where bodies line up and light is blocked, to describe a painful relationship. The other person is the sun, and the speaker is the earth, circling someone who may not be giving anything back.
The feelings are tangled. There is longing, since the speaker wants those rare, dramatic alignments, and there is hurt, shown in the question "am i just a toy to you." Without this person, the speaker's world feels chaotic. By the end, though, the tone shifts toward resolve. The speaker says they deserve those eclipses, and if they can't have them, the word "toxic" and the thought of leaving appear.
The mood is wistful, anxious and quietly brave. The speaker still sounds unsure, asking "would it be?" even while deciding to walk away.
