Really like the structure of this.
Like the repetition of 'helpless', I didn't see it straight away but when you step back and look at the outline, there it is.
'it's baby bed' - its. Just a suggestion.
Really like 'I am Europe, made the less.' It reminded me of that line in
Anthony & Cleopatra: 'For I am Egypt's Queen.' A bold statement of being; of pride. Brought low. There's something Shakespearean in that line. Evocative.
'I am a woman, becoming smaller.' Toyed with the statement 'I am woman' - drop the indefinite article? But then I found I had Helen Reddy going round in my head

Might be a risk worth taking.
Is the break in structure deliberate, or should 'Safe' be on a separate line so that each verse ends with a single word? Not that I'm one for routine, but I think the A-symmetry bothers me slightly. Although giving the word 'Safe' that much attention might go against the theme of divorce.
Nice finish.
