Many partners of addicts have told me they feel bad about themselves for staying in the relationship because of the betrayal they’ve experienced. They imagine that the people who know their past judge them to be stupid for staying with the person who’s caused them so much pain. I often counter this thinking, explaining that leaving may seem quick and easy because they can pretend they’re okay and the problem has disappeared. However, if you leave your relationship, you’ll be stuck with your pain and sorrow without the person you loved to help you sort it out. Why is this true? Because even though it feels as if your pain comes from your partner, it’s actually coming from inside you.
