Starfield:Romance

Romance is an option in Starfield to take your relation to your companion to a romantic level. There are (currently) only 4 romance options available.

How to Romance
In short, take them with you everywhere. In order to romance a companion you have to raise their affinity. This happens when you do things that agree with their personalities. This mainly pertains to dialogue choices and event actions(killing someone, sparing their life, etc). As their affinity rises, they will offer various dialogue interactions that are specific to them and their background. In some of these there will be dialogue options for [Flirt]. As their affinity rises even further you will see dialogue options for [Romance] which will officially make you a couple and eventually lead to their story mission being unlocked. Once you have completed their respective story mission, then you will have more dialogue options which will include [Commitment]. By this point, your affinity should be high enough that they will say yes to your marriage proposal and after some time, they will approach you to go get married.

The use of the Paramour consumable will also increase the affinity gained by your companion for 10 minutes.

It is worth noting, the game time-gates many interactions that further the romance option. So, if you feel stuck, simply give it some time and proceed with other things.
