YOU ARE NOT TO BLAME AND YOU DIDN'T ATTRACT THIS INTO YOUR LIFE – Though these behaviors from your partner scars you deeply now, there is nothing you did that caused the addict to act out. You couldn't have stopped it. You can't cure or control it. It's entirely on your partner's shoulders.
Sex addiction usually has its roots in adolescence, and they were likely acting out in their addiction before you met them. There is nothing you can do to stop an un-recovered addict from seeking his drug and using.
You are empowered to have boundaries around their sobriety, recovery efforts, the fruits of recovery (change and growth) and how they interact with you.
