matchstick men

[THATWACOKID]

ok, so i just got done watching the movie matchstick men. i thought it was pretty good, but the last part completely lost me. were the psychiatrist, his partner, his daughter, and the guy he tried to con all in it together? the part that confused me the most was when he goes back to see his wife and she says that she lost the baby before she was born. then he sees his daughter a year later all grown up and she acts like everything really did happen.

anyone who's seen this please help me make some sense outta this.
