Love doesn't work when you treat it like a bank note, to be collected by the creditor when due. No one is the debtor, no one is the creditor. If you love your children, you don't do things that cause them to cut you off. Likewise, if you love your parents, you don't cut them off when they they don't do what you want. You forgive.
Every day, you choose to be a part of each other's life, and help each other get through life. How you do that changes through life. Not every child will be successful, self-actualized or achieve anything near their potential. Not every parent will make good choices, be successful, or even be worthy of respect. People mess up. They make mistakes. The way love really works, is you forgive. And keep forgiving. You keep the relationship alive. You celebrate the good, and you sympathize through the bad. The greatest gift a parent can give is loving their child despite it all, and the greatest gift a child can give is loving their parents despite it all.
It is, of course, possible to love and damage a child at the same time. When that child becomes an adult, they have every right to recognize that the power dynamic has shifted, and they can establish any boundaries they see fit - including cutting them off.
