Multiplicity
(1996)

After his wife leaves him, Doug Kinney (Michael Keaton) and his three clones fix the old house.  Doug asks Laura (Andie MacDowell) to come back.  She sees the house and returns to Doug.  The entire experience has taught Doug to prioritize better and put his family first.  The three clones go to Florida and start a pizza business.
