The only way that an addict (or anyone else) in your life can continue to use and manipulate you is with your permission. Many loved ones of addicts are terrified of having to deal with conflict – so they say “Yes” when they really want to say “No.” But when they learn how to deal with conflict assertively and effectively with healthy boundaries and consequences that mean something to the addict, they will no longer put themselves in a position to be manipulated.
