Andrew and Joey

From Goodreads:

In Jamie James's funny, bittersweet debut novel, a gay couple's romance and trial separation unfolds through a series of e-mails to each other and colorfully assorted friends and family, vividly capturing the essence of a millennial love affair.

Joey, a hot-blooded Cajun choreographer, and Andrew, a perpetually unemployed upper-crust, All-American Asian, seem to have little in common except a college alma mater, and fourteen tranquil years of gay marriage. But that's about to come to an end now that rising star Joey Breaux has landed a sought-after grant for a year of study and dance in Bali -- with his reluctant lover in tow.

As Andrew obliviously sets up housekeeping in Bali, Joey plunges into a whirlwind of dance and debauchery, convinced that Andrew will understand and overlook his indiscretions. But when a wild fling with a young Indonesian pushes Andrew too far, the only solution seems to be a separation.

From Bali to San Francisco to Greenwich Village, Andrew and Joey pour their hearts out to far-flung confidantes -- even occasionally, to each other. As their electronic messages criss-cross the globe, the two men edge even closer to the surprising truth about the relationship they'd both taken for granted, assuming -- perhaps foolishly, perhaps not -- that it would last forever.
