These days, many couples live together, sleep together, and spend a lot of time getting to know each other before their wedding day. And still, getting married is more than just a symbolic step - it can change a lot.
To learn more about those potential changes, we checked out a Reddit thread where hundreds of people posted about the biggest ways their relationship changed after marriage - and how they adjusted. Some of those changes are more superficial (one Redditor posted about getting used to wearing a wedding ring); others go deeper.
We pulled out the most compelling and most surprising responses, so you can know what to expect if you're thinking about tying the knot.
