Is there a way to have a "domestic relationship" but, still call it a marriage?

Sometimes I wonder if my fear of getting married, is just the idea of everything that goes along with being in one. Which, is, essentially, just a domestic relationship, on steroid. Just like friends with benefits, is just a friendship on steroids (a relationship, without the relationship "label").

So, while I would like to live with a girl and show I can be committed to her, but, still actually call it a marriage, just not actually be "in a marriage"
