The Five Stages Of Relationships

Relationships don't follow a linear script, but they do tend to cycle through recognizable phases

I first ran into this framework when trying to make sense of a client project that collapsed six months in. I was consulting for a company building a shared project management tool, and the two founders couldn't stop clashing over features. Everyone kept saying they were stuck, but nobody could articulate why. Someone referenced the Kübler-Ross model as applied to partnerships and it finally made sense of what was happening. Not perfectly, but enough to move forward. The original model was developed by Elisabeth Kübler-Ross in 1969 as a way to describe how people process grief and loss. She identified five stages: denial, anger, bargaining, depression, and acceptance. Over the years, therapists, coaches, and relationship educators adapted the framework to romantic partnerships, business collaborations, friendships, and even your relationship with your own habits. The adaptation isn't academically rigorous. It's heuristic. But it's useful because it gives people a shared vocabulary for what's happening when things go sideways. Here's how the stages actually play out in practice:

Stage one is denial. You ignore the friction. Maybe you're dating someone and they leave dirty dishes in the sink for three days straight. You tell yourself it's fine. They're just busy. It'll pass. In business partnerships, denial looks like agreeing on a contract term without reading the fine print and pretending everything is solid. I once watched a co-founder sign a revenue-sharing agreement that literally said "net profits after all expenses" without clarifying whether their own salary counted as an expense. We spent four months trying to untangle it. Nobody admitted the problem existed until month five. Stage two is anger. The avoidance stops working. Reality starts pressing against you and you push back hard. This is the fighting stage. The messy, unglamorous, exhausting part. People often think anger means violence or shouting, but in most relationships it shows up as passive aggression, silent treatment, resentment building through small complaints, and that feeling of being exhausted by the same conversation for the tenth time. I've seen couples reach this stage within weeks of moving in together. One partner thinks the other is inconsiderate. The other partner thinks the first one is controlling. Both are partly right. Neither will admit it at this stage because admitting it feels like losing. Stage three is bargaining. You try to negotiate your way out of the discomfort. This can look like offering favors, making promises you don't intend to keep, or constantly recalibrating your behavior to avoid triggering conflict. In business relationships, bargaining manifests as scope changes, renegotiated deadlines, and promises from both sides to "do better" without any actual system in place. I worked with a marketing agency that was in full bargaining mode with a client for eleven months. They kept offering discounts and extra deliverables instead of pushing back on the unrealistic expectations. It didn't work. The client wasn't trying to be reasonable. They were testing boundaries. The agency eventually walked away, but it cost them nearly $40,000 in write-offs.

Stage four is depression. This isn't clinical depression necessarily. It's the energy dip that comes after prolonged conflict. You stop trying to fix things. You go through the motions. You feel tired of the relationship itself. In my experience, this is the stage where most relationships either stagnate or snap. People stay because leaving feels harder than staying. I've sat in sessions where clients described this exact feeling — not sad, not angry, just hollow. The worst part is that depression in relationships is quiet. There's no dramatic event. Just the slow erosion of investment. Stage five is acceptance. You stop fighting reality. This doesn't mean you approve of everything. It means you see the situation clearly and choose how to respond rather than react. Acceptance can lead to genuine repair and growth. It can also lead to a clean, respectful exit. Both are valid outcomes. What matters is that you're operating from clarity instead of avoidance or desperation. There are a few things most people miss about this model that took me years to figure out:

First, the stages aren't sequential. People jump around. You can enter bargaining before you fully process anger. You can cycle back to denial after reaching acceptance when a new stressor hits. A healthy relationship isn't one that avoids these stages. It's one where both people can name what stage they're in without turning it into a weapon. Second, the model assumes a certain baseline of good faith. If one person is actively abusive, manipulative, or narcissistic, applying this framework can actually harm you. It can make you rationalize staying in a toxic situation because you're convinced the other person will eventually reach acceptance. They won't. In those cases, the only productive path is exit, not stages. The practical application is straightforward but not easy. When you notice tension rising, name the stage out loud. "I think we're in denial about this problem." "We're arguing because we're both angry and neither of us is listening." Just saying it changes the dynamic. Most conflicts escalate because both people are acting out the stage without awareness that a stage exists.

For business relationships specifically, I recommend establishing a check-in protocol before you hit stage two. I set up weekly 15-minute alignment calls with every partnership I've entered since 2018. The agenda is simple: what's working, what's not, what do we need to adjust. It sounds boring. It saved me from at least three relationships that would have gone South. Most people skip this because they want the relationship to feel natural. Natural doesn't protect you from poor communication. Structure does. The main limitation of this framework is that it was designed for grief, not relationships. It doesn't account for power imbalances, trauma responses, or cultural differences in conflict styles. If you're working within a relationship where one person holds significantly more power — financial, social, or emotional — the stages become distorted. The less powerful person may skip from denial directly to a survival-mode bargaining that looks nothing like the model describes. Be aware of this. The framework is a map, not territory. If you want to dig deeper, the original work is in Kübler-Ross's 1969 book On Death and Dying. For relationship-specific applications, look into work by John Gottman on conflict patterns and the concept of "repair attempts" during arguments. Those frameworks are more evidence-based than the five stages adaptation but they complement each other well enough that I use both when advising clients.
