Struggling with addiction while balancing a romantic relationship can be quite challenging. A substance use disorder does not necessarily stop a person from having successful relationships. However, healthy romantic relationships require communication, mutual respect, trust, individual identities and care. Having a substance use disorder can make it difficult to tick all of these boxes. For many, toxic relationships & addiction go hand-in-hand. Despite one's best efforts, even once healthy relationships can sour when addiction is involved.

Why it matters

Addiction affects the addict and those closest to them. In order to sustain their habit, addicts and alcoholics often engage in behaviors that negatively affect both themselves and their loved ones. Just like a toxic relationship between two partners, many addicts and alcoholics find themselves in a toxic relationship with drugs and alcohol. They continue to use compulsively, despite the negative consequences drugs and alcohol have on their lives. If left untreated, the complex brain disease can cause irreparable damage to a person's life, family, and romantic relationships.

The details

There are many negative behaviors associated with both toxic relationships and addiction. This doesn't make all addicts inherently bad people. However, the compulsion to seek out drugs and alcohol combined with the avoidance of the feelings that caused the addiction can lead addicts to behave in unhealthy ways. Two behaviors common among addicts are lying and manipulation. Some lie and manipulate to protect their addiction and themselves from the consequences of their behaviors. For instance, the addicted partner may lie about using, their desire to quit, their whereabouts, and how they are spending their money. They may also manipulate their loved one with false accusations, and by guilting and blaming the other for their issues. Both of these behaviors usually occur as a way to avoid addressing the addiction head on. Constant lying and manipulation can damage trust, a core tenet of a healthy relationship.

  • Addiction and toxic relationships can occur at any time, but the behaviors and patterns often develop over an extended period.
