Our reading
An editorial interpretation.
The speaker plans to go to a woman's home, wait until she lets them in, and refuse to leave until the relationship is restored. The repeated declarations emphasise determination, but also pressure: the plan treats continued presence at her door as a means of obtaining the desired answer.
