Mate, I think I made it clear several times that marrying for a visa is out of question. EVER.That's a retirement Kitap. A WNI sponsored Kitap may differ.
Ooops, marrying about love ...
My companion and me live together since over 11 years.
But I don't touch her freedom, and she doesn't touch mine...
Keep it simple.
And I am a lonesome cowboy (not a lonely...) and it suits us fine.
