You always have to set boundaries and even then, boundaries are shaken and have to be rebuilt stronger than before with certain people.
Always set boundaries. It’s called self preservation & self love & self care. Without self, how can we be expected to help others? We must protect our own temple before attempting to help rebuild others. ~ Amber Van Sweden
Taking advantage means a selfish way of thinking only himself or themselves. It doesn’t help at all. The sure thing is to learn to say no if someone makes you feel uncomfortable in a given situation or decision learn to trust your instinct to avoid being abused. ~ Ram Angeles
Respect people’s feelings 
You do not have to make your children into wonderful people 
Don’t remove the wrong people in your life with anger 
Nobody is worth stressing over
