Protecting a secure attachment style is important because it is possible to become anxiously attached, even if one had a stable attachment framework in childhood.

“And some of you may be familiar with circumstances whereby people who are securely attached, either because they grew up in an environment where secure attachment was cultivated, or because they developed that on their own, can also migrate out of the securely attached category into insecurely attached, or into avoidant types of attachment styles as teens, or as young adults, or as adults at any age or any stage of life, by virtue of being with somebody who has a different, perhaps less adaptive attachment style, right?”
