How do you know if your relationship is one-sided?

A relationship is one-sided when one person is consistently doing most of the starting, planning, apologizing and adjusting, and it stays that way across weeks, not just a rough stretch. If that’s you, the answer is simpler than it feels: say what you’d like to be more shared, give it a few weeks, and watch whether anything actually moves.

Kwabena, 36, a structural engineer, has been with Tove, 34, a product designer, for a year and a half. Neither of them exists; they’re sketched here to make the idea concrete. Over the last two months he’s booked every dinner, organized the trip to see her parents, and been the first to say sorry after both of their arguments. When he mentioned wanting to talk about moving in, she said “after launch week.” Launch week was three weeks ago.

Pull the threads apart

What happened: two months of him initiating nearly everything, and one postponed conversation. The reading: she’s less invested than he is. The fear: he’s giving another year to someone who’s halfway out, and he’ll be starting over at 37. The next step: count what’s actually happening, then name it directly.

The reading might be right. It might also be a heavy quarter at her job. Those look similar from the inside, which is why counting matters.

What “one-sided” actually means

Therapist April Eldemire suggests treating a relationship as 100/100 rather than 50/50: both people bring their full effort, rather than splitting a fixed amount.1 A one-sided relationship is when that stops being true for one of you.

Writing for Verywell Mind, Kendra Cherry lists the signs most people recognize: you start almost every conversation, plan most of what you do together, are usually the one who apologizes after conflict, and cover more than your share of shared costs.2 Eldemire’s list overlaps, including frequently apologizing for things.1

What research says about the gap

Sociologists have a name for the tilt: the principle of least interest. In a study that followed dating couples over several years, Susan Sprecher, Maria Schmeeckle and Diane Felmlee found that unequal emotional involvement was common and tended to stay stable over time.3 The less-involved partner felt more control over whether the relationship continued. Couples who felt equally involved were more satisfied and more likely to stay together.3

That’s worth sitting with. A gap isn’t automatically a crisis, and many couples have one. But if it stays fixed, the person who’s less invested quietly holds more of the steering wheel.

A related study, also by Sprecher, looked at fairness. People who felt they were getting less than they gave were less satisfied, less committed and more likely to break up.4 Here’s the useful nuance: feeling shortchanged at one point didn’t do much to predict later drops in satisfaction.4 So the imbalance and the unhappiness travel together, but the study can’t say one causes the other. Sometimes unhappiness makes the scales look worse.

Commitment research adds one more piece. In work on the investment model, commitment went along with satisfaction, how much people had put in, and how weak they felt their alternatives were.5 It’s a useful check on your own side. “I’ve put so much in” is one reason to stay. It’s not the same as “this works for me.”

The difference between a season and a shape

Busy shrinks the time someone has. A one-sided pattern shrinks what they do with the time they have. A partner in a brutal quarter still asks how your presentation went. They still say “this week’s bad, but let’s do Saturday.” The effort is smaller, but it’s pointed at you.

The shape looks different: things you ask for get postponed without a new date, apologies only travel one way, and the planning never shifts, even in quiet weeks. “After launch week” with no new date is a calendar invite nobody sent.

What to do tonight, and this week

Tonight

• Write down the last month honestly: who started, who planned, who apologized, who rearranged. Don’t send anything yet.
• Notice your own part. Sometimes the person who plans everything has stopped leaving room for the other to plan.

This week

• Say what you want first, then ask what they want. “I’d like planning to feel more shared. What would make that easier for you?”
• Propose a rhythm. Eldemire recommends setting dedicated times each week to talk about the relationship, not just when something breaks.1
• Pick one specific thing they could own, like next month’s dinner with friends, and let it be theirs.
• Then give it three or four weeks. Watch follow-through, not promises.

Kwabena asked Tove for a Sunday check-in. The first one was awkward. By the third, she’d booked a weekend away without being asked, and they’d set a date to talk about the lease. Not every version ends like that. If nothing shifts after a clear ask and a few weeks, you have your answer about how this relationship runs.
