When to Get Engaged: What the Research Actually Says About Timing

Getting engaged is one of those decisions where everyone has a strong opinion and most of the opinions are essentially useless. "When you know, you know." "Don't rush it." "You don't want to wait too long." These sentences contain almost no information.

Research on engagement timing and relationship outcomes is actually quite rich — and it doesn't say what most people expect. Here's what the data shows, and what it means for making a decision that's right for you.

Does length of dating before engagement actually predict marriage success?

Somewhat, but not in the way most people assume. Several studies have found that couples who dated for two or more years before getting engaged report higher marital satisfaction than those who got engaged within the first year. A Emory University study of 3,000 Americans found that couples who dated three or more years before engagement were 39% less likely to divorce than those who dated under a year.

Importantly, these are population-level correlations. Couples who get engaged at six months and are still together thirty years later exist in large numbers. The research tells you something about average outcomes, not your specific situation. But averages carry real information, and "we've been together six months but it just feels right" is a sentence worth interrogating carefully.

The "sliding vs. deciding" problem

One of the most important research concepts for engagement timing comes from Scott Stanley and Howard Markman at the University of Denver. They identify a pattern they call "sliding versus deciding" — the difference between couples who consciously and explicitly decide to escalate commitment versus those who drift into it through a series of individually small steps.

Their research found that sliding — rather than deliberate deciding — is associated with lower relationship quality and higher divorce risk. This is partly because when you slide into engagement, the underlying conversation about whether this is actually what you both want, and why, often doesn't happen. You get engaged because you've lived together for two years and it's "the next step," rather than because you've both explicitly chosen each other with clarity.

This is relevant to the moving-in-together milestone as well — the same research suggests that couples who move in together before any explicit commitment conversation are more at risk than those who move in as a deliberate step towards marriage.

What conversations you should have had first

Timing isn't really about months. It's about knowledge. The question isn't "have we been together long enough?" but "do we actually know each other well enough for this to be a real choice?"

Research on values alignment consistently identifies these topics as the ones that cause the most friction in long-term relationships. Getting engaged before you've had these conversations isn't impossible — but it's a bet that you'll navigate them well under the higher-stakes conditions of marriage, which is a riskier proposition than having them first.

The external pressure problem

One of the most consistent findings in the engagement research is the damage done by getting engaged under social or external pressure. This includes the "we've been together four years and people keep asking," the family pressure around age, the sense that the relationship is going backwards if you're not moving forwards.

The same applies to the opposite pressure: feeling like you're being disloyal by not being ready, or that wanting more time means something is wrong with the relationship. Sometimes more time is simply accurate information about where you are — not a problem to be solved, but a reality to be honoured.

Age, life stage, and what they actually predict

Age at engagement is one of the most researched variables, and the findings are fairly consistent. Engagements before age 25 are associated with significantly higher divorce rates than those after 25. This isn't about immaturity in a moral sense — it's about brain development (the prefrontal cortex, which governs long-term decision-making, doesn't fully mature until the mid-twenties) and the degree to which identity is still in formation.

This matters particularly because growing together over time requires that the people doing the growing have some stability in who they are. Couples who form their adult identities together can do it beautifully — but the research suggests the risk of growing in incompatible directions is higher when both people are still fundamentally figuring out who they are.

The proposal itself: a brief note

The way an engagement happens matters. Research on relationship satisfaction finds that feeling genuinely wanted — not just asked — is a component of long-term satisfaction that people often underestimate at the moment. A proposal that's co-created between two people who've already had the substantive conversation about their future is quite different from a surprise proposal in a context where the substantive conversation hasn't happened yet.

Surprise proposals can be wonderful. But the "surprise" should be about the moment, not the decision. If the engagement itself is a surprise — if one person is proposing without certainty about the other's readiness — that's a category error dressed up in romance.

So: when should you get engaged?

When you've had the conversations. When you've seen each other across enough contexts that your compatibility is based on reality rather than projection. When the decision is mutual and deliberate rather than drifted into. When neither of you is primarily motivated by external pressure, fear, or the feeling that it's time rather than that you're certain.

The research suggests that two years of dating tends to provide enough time for most couples to achieve this — but some couples get there faster, and others need more time, and neither is a verdict on the relationship. The quality of what happens during that time matters far more than the quantity.

The most important question isn't "when?" It's "have we actually chosen each other, clearly and explicitly, with our eyes open?" That question doesn't resolve itself by the passage of time. It resolves through honest conversation, genuine vulnerability, and the kind of knowing that comes from having shared real life — not just good times — together.
