not sure if that's legal...

• Dear Anon,
  
  Sorry to say, but what you're suggesting is, well, probably against the law. If you're living together now in the US, then it may (emphasis on MAY) be possible for you to move as a couple to NL if one of you qualifies for the local eased work permit program.
  
  A number of European countries, in fact, do recognize unmarried partnerships. There is some information on the two following links:

  You would need to be able to show the right evidence to authorities, but others have done it and it's worked out.
