Ludwig and his daughter Marie Louise have never had a close relationship.
When Marie was a child, her father didn't know what to do with her, because he didn't like little children at all. Maybe he was even offended that Marie survived, but his beloved son Carl Emanuel had to die.
After 1889, Marie still had contact to her parents. Above all, she loved her mother. Henriette died in 1891. Since then, Marie and Ludwig haven't seen each other regularly.
It also hurt Marie's feelings that Ludwig married Antonie Barth only one year after her mother's death. She sometimes visited the couple. One evening in 1897/98 Marie Louise heard her father (who was very jealous) and Antonie argue heavily. Marie was side with Antonie. Because of that Ludwig became that angry that he forced his daughter to leave his house. They've never met again.
Ludwig also didn't accept Marie's plan to write a book about her aunt Marie of Naples ("Die Heldin von Gaeta"). Ludwig and the former Queen were very close in their later years and that's why Ludwig was afraid of rumours concerning his little sister.
Marie read about her father's death in a newspaper in 1920. But it's quite interesting that she wanted to be buried next to her father at the Ostfriedhof in Munich.
Hope, I could help.
BTW: Eugenie, your English is perfectly okay.
Welcome.
Marie
