(((Hugs to you)))
IMOAE, when the addiction is in complete control of someone, it will continue to try to manipulate you to stay engaged. The addiction needs an enabler in order to thrive because the person it lives inside is under it's control.
The co-dependant's addiction will also seek to thrive inside you and enable the other's addiction, unless you focus on becoming free of it. No contact means no manipulation.
At this point, you cannot help each other and can only focus on your own "monster" in order to become whole, free, and balanced beings again.
It really does suck.
