Keeping a Clivia as an indoor potted plant is much different than growing out outdoors in its native environment. Given your location in WA, you will have to move it indoors when temps drop to 50 degrees F. Outside it should be in shade at all times.
When you move it indoors, keep it in a moderately sunny location, but gradually reduce the watering until you let it dry out completely for about a month in mid-winter. This semi-dormant period will help set it up for flowers next spring.
You can repot in spring, but only if it is very potbound. Repotting or moving to a pot too large cam deter flowering. In general, it is best to err on the side of dryness with a Clivia. Overwatering, overpotting and over fertilizing will discourage blooms. So, yes, it does well with neglect.
