Avoiding Triggers that can generate negative karma

I have a problem that I am currently facing. There is a certain person in the family that triggers me and due to their actions I feel very angry and generate negative mind-states. The strategy I have adopted is to avoid this person all together , to the point of not even seeing them. I find that this helps me to keep calm and avoid negative mind states. Is this a good way to go about this situation? Can we avoid all triggers that generate negative mind states. Does that help in spiritual development?
