a new atheist and marriage

[Seraphina]

A rational, intelligent and intellectually honest person, one would hope. Armed with evidence that such a relationship is demonstrably harmful. That's who you could be, to judge.

What's harmful about a traditional relationship?

In relation to the original post where both participants enjoy the traditional male or female role in the relationship.

Saying someone is "confined" to gender conforming roles makes it sound bad, but being confined to what you want, until/if you change your mind, is just part of making decisions. 

Someone who's a dominatrix lesbian with a female partner is confined to that role for as long as they participate in it just as a female who is traditionally married and cooks, cleans looks after kids while he goes to work is confined to that role.

And thank whatever it is that you thank that we live in free societies that allow couples to decide between themselves how to live. I personally choose partners like me that don't care for rigidly defined gender roles. And who knows, the couple in the OP may end up that way too. But atheism does not include a set of rules that men and women must abide by simply based on their sex organs nor does it require that couples have non-traditional roles.
