Given the following context:

Dr. Sullivan Travis (aka "Dr. T.") (Richard Gere) is a wealthy Dallas gynecologist for some of the wealthiest women in Texas who finds his life beginning to fall apart starting when his wife, Kate, suffers a rare type of infantalizing syndrome of wealthy women, receding into a childlike state and, after she disrobes in a shopping mall fountain is committed to the state mental hospital.  When Dr. T visits  Kate , she rebuffs his kisses as improper and he sees her pre-teen psychic age cannot be brought back to adulthood by his affection. Dr. T's eldest daughter, Dee Dee, is planning to go through with her approaching wedding despite the secret that she is romantically involved with Marilyn, the maid of honor. Dr. T's youngest daughter, Connie, is a spunky conspiracy theorist who has her own agenda including sharing with her father how she discovered Dee Dee and Marilyn are lovers. 
While Marilyn is on his examining table for the first time, she surmises her condition is caused by the stress of being the maid of honor for her friend Dee Dee. Dr. T  realizes she is Dee Dee's lover and becomes embarrassed mid-examination asking Carolyn, Dr. T's loyal secretary, (Shelley Long) to finish.  
Carolyn has romantic feelings for him, which are not mutual: in a farcical scene at the workday end, she locks the office door and gives him a shoulder-massage from behind his chair, secretly disrobing while emphasizing his need for a loving wife. Refreshed but unaware of her intentions , he goes to the coat closet, turns and finds she has vanished. From under the desk, she says he never empties his trash baskets. Approaching the desk he glimpses her state of dress and quickly leaves.
Dr. T's sister-in-law, Peggy, meddles in every situation she stumbles into.
