could someone plz tell me how the movie ends

Yes, X and Andrew end up together, but it's a cliffhanger because it looks as if Andrew is going to move out and live with Matthew, the gay brother of Jill, the woman to whom Andrew was engaged at one time. And--guess what? Joey goes to college. The three are still living as roommates two years after the pivotal events of the story, and it appears that X is writing on his laptop a novel based on the experiences he's had. Perhaps we're to see the movie itself as the book X eventually wrote. It's a nice ending, a happy ending, an ending I wanted to see. It's a fine film.
