"Men's fantasy"
I just saw this movie for the first time. And the part towards the end where Rob tells Laura why men cheat, because they chase a fantasy with a girl who brings no problems to the table, that relationships are problem-free in his fantasies, struck a strong nerve with me. Moved me to tears. I could never understand the rationale behind it. If you don't remember this scene, give the movie one more shot and ponder his lines!
