Is Duality over idealised?

[Dudette88]

I am ILE and the husband is SEI. While all aspects of duality perfectly apply to our marriage, we both couldn't help but wonder 'doesn't every couple experience this?' We've been married 15 (kick ass) years (3 children in tow) and are high school sweethearts. We are eachother's 'onlies.' I figured we might be abit skeptical because we have no past romantic relationships to compare it to. Is a romantic duality relationship really all that different from other healthy romantic relationships? I've read it requires much less work. I can't imagine having to put in more than we do, granted it is very easy to be around one another. I just assumed the blurring of identities and unexplainable comfort happened in all good relations...

Just interested to see if others who have experienced various relationships could explain, perhaps?
