1. Husband wants the wife to abort her child because they are too poor and cannot afford to support it. Wife thinks otherwise.
2. tense, lingering hope
3. I think it's fine as is, though saying 'fetus' as the word itself kind of makes the passage too direct. It kind of feels like everything is revealed in that one line instead of letting the reader figure it out.

Great piece though. I really like the flow and how you revealed the story little by little :]
