Town & Country(2001)

A comedy about life, love, friendship, having everything and not getting caught... At least that's the way successful architect Porter Stoddard has been living his life. However, when his best friend Griffin is caught cheating by his wife Mona and an ugly divorce drama begins to unfold, Porter begins to re-evaluate his sturdy relationship with his wife Ellie in terms of his own dalliances with a beautiful cellist named Alex. Suddenly confronted by his own wife's suspicions, he decides to come clean--realizing that it's his wife that he truly loves. But is this revelation strong enough for Porter to commit the rest of his life to true monogamy?
