Why is Jane Austen considered a Romantic?

Jane Austen was a sort of realist who wrote about things that were romantic.

Realists tended to write about the harsh realities of life.

Romantics tended to write about heroic people in intense situations.

Jane Austen wrote about ordinary people falling in love and getting married, the difficulties they go through, their failures and their successes. Her characters were very realistic in the sense that they seemed like people we all know. The parts of their lives she focused on were their romances.

I suppose she was neither. She was unique, and had a style of her own.
