There is a saying in recovery rooms, no romance in the first year of recovery. Love and sex are common hurdles to recovery. Trina and Charlie fell in love in high school, and after years of using drugs together, Trina eventually got sober, and charlie wasn't far behind. Their journey has been filled with a lot of pain and suffering, including losing their children to child services.
They are now sober and expecting another child; they owe this new life and freedom to recovery and sticking to the principle of recovery first, before each other.
