Definitely getting better. Some suggestions:
S1L2: consider "run steadily from wounded eyes". Knowing the color of her eyes doesn't add to the poem, while describing the pain seen in them does.
S1L3-4: That the mc doesn't know why is not really supported by the rest of the poem.
S2: Still love this.
S3: This seems to be dragging things down. It feels too "common" to me. The poem needs what it is saying, but I think it could be said better. Again, think more vivid. Some words that come to mind: battered knees betray untold second chances foolishly spent. That may be overkill, but hopefully you get the idea.
S4L1: "I'm sorry does not atone." This flows off the tongue a little better than "doesn't atone".
I'm with Kate that I don't think you need the other stanza.
Good progress. Keep at it.
