Hello, Mira Vos! With your positive attitude, you'll probably make lots of friends here. Two thousand dollars a month is enough to have a very good life here - very good, indeed. No second-rate restaurants.
Sounds like a great adventure for both of you. And if you do go back to the US, you'll probably see it with new eyes. Living in a third World country increases appreciation for many things we take for granted.
Best of luck....
