Her husband gave her lessons how she had to fulfill her duties as an adult. The Princess seems to get a serious make-over and start to get glamour allures, which she showed of to anybody who liked (and didn't like), which caused the Emperor to get some misgrievings with this couple. This lifestyle worried Louise's mother, Queen marie-Henriette, who usually received full reports from her Habsburg relatives on her daughters scandalous conduct. Marie-Henriette did everything she could to make her daughter change her lifestyle and live a more sober life.
In the mean time her husband merrily went on partying as he did before his marriage, he didn't take his vows too seriously and is terribly promiscuous. Slowly the first cracks start to appear in the marriage. Another problem was that the Princess came into financial troubles due to her lifestyle, and her husband who slowly estranged from her wasn´t willing to pay her debts anymore.
Louise now took several lovers herself but finally found her true love in the person of the Croatian count Mattacic, whom she met at the Prater. A romance started which wasn´t kept very discrete. A vindictive Archduke Ludwig-Victor, turned to his brother the Emperor and urged him to discipline Louise, but Louise still failed to realise the seriousness of the matter.
She fell completely from grace with the imperial couple and her father chose the side of Louise´s husband instead of that of his daughter. Louise decided to chose for her count, dispite of everything. Philip felt that he had to defend his honour and entered into a duel with Mattacic, which he lost. Louise´s triumph was shortlived only as she came into serious financial troubles as her husband refused to give her even a penny.
