For a woman to decline Marriage is still hard in India. This "first" of its kind marriage in a great act of courage. I was not familiar with the word or concept of sologamy - the concept is logical at some level and not at others. It begs the question of what is the operating definition of marriage these days when society allows for a variety of  "non-traditional" unions. To gain acceptance as another kind of marriage, there will need to be strength in numbers. If even say 10% of single women described their relationship status as "married to myself" it would no longer be something that could be ignored as some sort of distortion. For the longest time people have been described at being Married to their work for instance. It would be the hyperbolic way to describe their degree of engagement with said work if the person was married and had a family. 

Under those circumstances, one would conclude that this person valued their work over everything else in their life. However, if the person was single it would connote that they were completely fulfilled and occupied by their avocation and there was no space in their life for things like spouse, children and concomitant responsibilities. Either way this was never considered wrong or distorted - some people are just made this way, they need to focus on their life's cause. That would be a sort of sologamy too. Stripped of the ceremonial aspects not much that separates the two. It's just a matter of normalizing how one would describe their status to the world. Maybe we will get to the time when it becomes politically incorrect to get into specifics of how you and to whom you are married. For many that would be a welcome change
