Wouldn't Lilly have been sent away too?

The film is based on a true story. The book, written by Erica Fisher, was published in 1994, and is based on letters and documents and her interviews with Lilly Wust and some surviving friends and relatives in a mixture of documentary and fiction. Anyway, it is true that sheltering a jew would have been a reason to be sent to a concentration camp. It says in the book that the only reason why Lilly was not arrested was because of her four children. She also did not confirm the questions if she knew Felice was jewish, which may be a second reason. Even more surprising, she was actually able to visit her several times in police custody, bring her clothes and food before Felice was deported.

Lesbianism wouldn't necessarily mean a trip to the camps. Lesbianism was seen as a treatable mania by the Reich. Harboring a Jew certainly could have, but like was said, she was a mother of 4, probably even got a Mother's Cross, and could've convinced "investigators" she knew nothing of Felice's Judaism.

According to the book by Erica Fischer, Lilly's Gestapo interrogators allowed
her to go home, but made her sign a document stating that she understood that because she had harbored a Jew, she deserved to be sent to a concentration camp, but that under the circumstances that she had four young children to care for, they released her. She held a bronze Mother's Cross for her maternal contributions to the Third Reich.

The Nazi Regime regarded (German) motherhood and family very highly. This was always something that worked in Lilly's favor, as she received alot of food rations for her four children. The Nazi Regime also did not take seriously the concept of lesbianism, and so it was therefore not considered unlawful; however, homosexuality among men was punishable by incarceration and death.
