5 Reasons Moving in Together Before Marriage Is Still a Mistake

My wife and I moved in together about two and a half years before we got married. Even in today’s modern dating culture, there are still people who frown upon the decision to make that move. As it turns out, there is some science behind why you shouldn’t move in together before getting married. Here are five common pitfalls of jumping the gun on moving in together.
1. It Lowers the Urgency for Commitment
Many couples find that moving in together before they tie the knot lowers the urgency for any further commitment. Living together makes it feel like they’re already married, so what does a piece of paper change? Unfortunately, the lack of forward motion in the relationship can cause the couple to drift apart, and they remain stuck in a comfort zone.
2. It Blurs Boundaries Before They’re Clearly Defined
Marriage brings with it a shared understanding of roles, responsibilities, and long-term goals. But moving in together before marriage often means those boundaries are fuzzy or never discussed. Couples may assume things about finances, chores, or fidelity without ever agreeing on them. That’s a recipe for tension, especially when expectations don’t align. Clear agreements are harder to establish when the relationship itself hasn’t made a formal leap.
3. It Makes Breakups More Complicated
One of the strongest arguments against moving in together before marriage is how it complicates breakups. When you cohabitate, separating means not just emotional heartbreak, but financial and logistical chaos. Splitting up furniture, navigating shared leases, and possibly finding a new place to live can feel like a mini-divorce. As a result, people often stay in relationships longer than they should simply because it’s easier than untangling their lives. That kind of entrapment isn’t love—it’s convenience.
4. It Gives a False Sense of Security
Cohabiting may give couples a preview of what married life could look like, but it’s a poor substitute for the real thing. Living together can feel intimate, but without the commitment of marriage, it’s more like a demo version than the full app. You might feel secure, but legally and emotionally, the relationship still lacks the foundation marriage provides. This false sense of permanence can blind people to deeper issues. Real commitment isn’t just about sharing space—it’s about showing up no matter what.
5. It Skews the Reasons for Marriage
When couples live together for years before marrying, the eventual wedding can start to feel like just another formality. Instead of entering marriage with clear purpose and intention, it may feel like “the next logical step” rather than a meaningful decision. That mindset can weaken the emotional bond that marriage is supposed to signify. A wedding should be a conscious choice, not a default setting. If you’ve already blurred the line between dating and marriage, it’s easier to overlook whether the relationship is truly healthy or just comfortable.
Why Slowing Down Might Be the Smarter Move
Moving in together before we got married was something that worked for my wife and me, but it’s not always the best option for other couples. Sometimes, it can force your relationship to stall out ahead of its time. Rather than rushing into living under the same roof, take the time to build on your relationship without living together. This can allow you to move forward with clarity and pinpoint what kind of future you see together.
