But the couple is still living together to this day. For a similar question, how do we know "were living" isn't correct? Yes they started living together before being engaged/married, but they are still living together to this day, so it is an action that started in the past but has not ended. Past perfect is for a verb that has started and ended in the past, but they are still living together, so what is wrong with the continuous tense C?
Hi
felixduan320, the sentence is not concerned about whether the couple is still living together
to this day; the frame of reference is when the couple made a final commitment to each other.
The presence of the word
before tilts the decision in favor of
past perfect. So, the two events are:
i) Making a final commitment to each other
ii) Living together
Since living together happened before/till the time that final commitment was made to each other, past perfect is appropriately used to depict the
earlier of these two events:
living together.
