yes.. if give birth don't want to take care well, might as well don't give birth..
please see below for my interpretation
from what i understand. it's about how to get along with the others.
亲人要生,family and relatives must maintain courtesy, treat like how you may treat someone you just met.
生人要熟,strangers you just met, must find common ground to build rapport
熟人要亲, those who already build rapport, must continue to maintain the relationship
then become 亲, go back to first line. it's a cycle.
of course, assuming what love.ly said below, you must not treat yourself badly first, and then you can start to treat others rightly.
修身齐家治国平天下
start from ownself mindset right.
so going to your question. if cannot live together in harmony then yes should move out. 亲人要生. when move out actually will cherish the time together more.
