Answer:
enabling
Step-by-step explanation:
An enabler is someone that facilitates a person's addictions by protecting the person from the adverse repercussions of his destructive behavior which in turn allows such behavior to continue.
Enabling can occur because you're trying to protect a loved one from an addiction and always intervenes to solve problems arising from his/her addictions.
Enabling can occur on different levels such as directly sponsoring a dug addict to get more drugs or ignoring telltale signs of addictions.
