As any builder will tell you, it is supposed to be the other way around. Measure twice, cut once. The point is simple: slow down at the beginning to avoid costly mistakes later. It minimises waste, reduces rework and respects the reality that once something is cut, it cannot be uncut!
Yet when it comes to relationships, and particularly long-term commitment or marriage, many of us do precisely the opposite. We measure once, if at all, and cut twice, or many times always hoping things will fit perfectly. We leap into commitment with enthusiasm, optimism and hope, while quietly ignoring how little we truly know about the person standing in front of us.
Buyer beware
With very few exceptions, you would not sign an agreement to buy a house without conditions of sale. At auction it’s ‘buyer beware’ so you are always advised to do as much homework as possible. You would not waive due diligence, inspections, or finance clauses unless you had an exceptional reason to do so. Even then, you would understand the risk you were taking. Those conditions exist for a reason. They are not signs of doubt. They are acknowledgements of reality to minimise pain later on.
Relationships, however, are rarely afforded the same level of care.
We commit emotionally, financially, legally, and socially to another person long before we have seen how they respond under pressure, disappointment, grief, boredom, or change. We often commit before we have seen how they argue, how they repair, how they apologise, or how they behave when things are not going their way.
Love is blind
Early relationships are deceptive by nature. Not because people are deliberately dishonest, but because the conditions are artificial. There is novelty, chemistry, optimism, and a strong incentive to present our best selves. The early stage rewards adaptability and suppression rather than authenticity. We accommodate, overlook, accommodate and we smooth edges. Best foot forward, hide our faults as best we can. We tell ourselves that love will sort the rest out later.
Marriage, or at least open-ended commitment, is often entered into during this phase. We formalise a future based largely on potential rather than a solid pattern derived from experience. We commit to a version of the person we hope will remain stable, while ignoring the fact that people change, circumstances change and unseen or ignored differences will probably emerge at some point.
Compatibility mode
This is particularly true when it comes to sexual compatibility. Desire, libido and intimacy are often assumed to align simply because there is mutual attraction. Yet chemistry at the beginning tells us very little about how two people experience desire over time. Many couples discover only after commitment that they have fundamentally different needs around physical intimacy, frequency, closeness, or autonomy and by then the cost of pointing out that mismatch becomes dangerously high.
The litmus test
Long-term relationships are not tested by romance and ideals. They are tested by monotony, stress, misalignment and growth in different directions. They are tested by illness, financial pressure, parenting, career changes, aging bodies, shifting identities and unmet expectations. Rarely do these show up in the honeymoon phase. Most of all, relationships are tested by how we change over time. Add to this an intrinsic human need for variety and its no wonder divorce and separation rates are so high – for those willing or able to move on. There are countless people trapped in relationships that have frozen over.
Yet we treat commitment as if it locks in certainty and banishes risk. A dead cert. A share that can only rise in value.
Put it all on red 13
We sign up to lifelong exclusivity, shared finances, shared responsibility, and shared identity without ever explicitly discussing many of the things most likely to strain the relationship later. Sex, money, autonomy, ambition, family obligations, personal growth and values are often assumed rather than explored. Silence is mistaken for agreement. The first on this list is the one least likely to be properly discussed. Many people would rather walk over hot coals that discuss sex. If hard to bring up at the start of the relationship then it becomes almost impossible a few years later.
There is a quiet belief that committing early creates security, that showing committment itself will make the relationship stronger. In reality, premature commitment often suppresses necessary conversations. Once the stakes are raised as time passes, honesty becomes harder. There is more investment to lose face starting over from square one. It is easier to compromise than to risk destabilising the bond we have already formalised. Just hold in there and hope for the best.
This is why measuring once becomes costly. Commitment does not make incompatibility disappear. It simply raises the price of discovering it later.
The modern marriage paradox
Modern marriage is often framed as a declaration of love rather than a legal and social contract. Romance is emphasised and celebrated through media and marketing narratives. The binding nature is downplayed. We talk about forever while avoiding the question of whether the agreement we are entering into will still fit the people we are yet to become. And, of course, who can know how the years ahead will change them? It is entirely possible to love someone deeply and still not be well suited to build a life together. Love does not guarantee compatibility.
Time to get the ruler out
Measuring twice before committing to the ‘cut’ of starting a new relationship does not mean withholding love or refusing commitment. It means allowing time and space to see the full person. It means observing patterns, not promises. It means having very uncomfortable conversations before they become unavoidable. The absolute deepest conversations around intimacy and desires and perhaps the most important. It means understanding that conditions are not a lack of faith, but an act of caring for the other and self-preservation. A sort of intimacy insurance policy.
Ironically, the same ‘measure twice cut once’ approach ought be taken before leaving a relationship. In some cases it may prevent an unnecessary ‘end of everything’ just because one aspect needs checking. When there is nothing to lose you may as well be honest about intimacy needs – you might find you were not alone.
We have normalised the idea that uncertainty in relationships is something to avoid; it looks like weakness, a fear of commitment. In reality, thoughtful hesitation at the outset can reflect maturity. It shows that measuring twice is wise, as any good builder will remind you.
