There are so many situation in which we had no choice as children. We simply lived by the rules we learned and adopted them as truths. As children, we didn’t have a choice but to be around people who kept hurting us, but as adult we do. Staying in situations and with people who are hurtful is an old rule we no longer need to live by.
There is no point at which someone tells that those rules no longer apply and we get to choose which ones we want to keep and which ones we want to let go. We often takes old principles to adulthood not fully realizing that we no longer have to stay in situations or around people that keep hurting us.
