Should You Marry Her?

Weighing the costs against the benefits

Marriage is a contract: you promise not to break up with your partner even if you later end up wanting to, and they promise the same. A wedding is a contract enforcement mechanism: by standing up in front of your community and declaring that you won’t leave each other, you make it harder to back out later. If you break up for frivolous or fixable reasons, your community will judge you. If you go to your friends for advice about your relationship struggles, they’ll be more oriented toward helping you make it work and less likely to suggest you leave. Your acquaintances will be less likely to try to tempt you away from your spouse, partly because others in your community will think they’re shitty if they do.

The main benefit of marriage is investment. When both of you are much more confident that the other will stick around for the long haul, you are incentivized to make investments in a joint life that wouldn’t otherwise have been worth it. This could look like buying a house or having a kid, dividing labor like life admin and fixing things and cooking to make joint life more efficient, or putting in the work to understand each other better and meet each other’s needs better.
Beyond that, I’ve found the emotional security of commitment creates room for a more radical trust and love. You allow yourself to sink into each other and extend deep roots in each other’s souls.

The main cost, assuming you plan to get married eventually, is that you might have found someone better. So how do you decide whether to commit to your current partner? By popular request, I’ve made up a brief guide. While this advice is gender-neutral, women generally know what they want and are ready to commit sooner than men, so it’s addressed to the confused rat boys in my life.

Once your girlfriend is ready to get married, you have three basic choices at any given point in time:
  • Commit to her now: pay the cost of forgone options, get the benefit of investment.
  • Break up with her now: pay the cost of searching for someone new, get the benefit of a different (and hopefully better) marriage starting in a few years.
  • Wait and see: pay the cost of delaying the start of marriage (and thus the accumulation of investment benefits), get the benefit of more information to make a better decision.
The first question is how long you should wait and see. A rough model is that you learn one more unit of information about your compatibility with your partner from every doubling of the amount of time you spend with them. My husband and I dated for about ~2.5 years before getting engaged, and we spent maybe 15 hours a week actively hanging out together over that period. So we’d already spent ~2000 full-time-equivalent hours together, or ~11 doublings starting from our first hour. A fifty year marriage would have been ~40,000 more hours, only another ~4-5 doublings on top of what we had already experienced (and as I’ll discuss below our marriage will probably be a fair bit shorter than that).

In general, if you’ve been with someone for a couple of years already, there’s not much point hanging around longer generically waiting for more information. You should have some understanding of what exactly you’re hoping to learn in another six months, and pay attention to make sure you’re actually learning something about that.

The second question is how your girlfriend compares to other women you could marry. Your wife will fulfill three main roles in your life:
  • Cofounder: Your wife will build a life with you. At a minimum, you’ll handle household maintenance and life admin together. Beyond that, what exactly you build together will vary — my marriage has revolved around working together to have impact, many are oriented around raising children, some are about creating rich shared experiences — so what you need from a cofounder will vary. But broadly speaking, you’ll want to feel like she’s competent and on top of her shit, that she’s bringing a lot to the table and your skillsets complement each other well, and that you communicate well and resolve differences constructively.
  • Friend: You’ll hang out with your wife more than you hang out with any other person. You’ll want to be able to laugh easily together, have a lot to talk about with each other, and do things together that you both enjoy.
  • Lover: Your wife will be the primary outlet for your romantic and sexual drives. You’ll want to find her charming and hot, you’ll want to be in love with her.
You probably have more evidence lodged in your brain than you appreciate, and some focused and organized introspection can probably move you. For example:
  • For the cofounder role, how excited would you be to literally cofound an organization with your girlfriend? Would you be excited to hire her? Would you be excited to work for her? How would she stack up among people you’ve worked closely with? What would her manager and coworkers say about her? Do you trust the way she makes important decisions? Would you trust her advice about your important decisions? What does it feel like to make decisions together and divide up the tasks of life together? If something happens to you, like you get hit by a car or your parent has a stroke and needs a lot of care, does it feel like a relief that she’s around to take care of things? Do you have similar aspirations for the life you want to build and a plan to achieve it together — if you want kids, are you on the same page about how much work each of you is going to put into childcare and do you think she’d be a good mother?
  • For the friend role, how much would you hang out with your girlfriend if it had to just be platonic (where would she rank in the rotation of friends you see every now and then)? What interests and joys do you share? What are the points of connection that seem rarest and most precious? What are the interests and perspectives you don’t share with her that you really wish you did?
