The REAL Reason Jana 'Cinderella' Duggar Never Got Married Like Her Younger Sisters

Fans have dubbed lonely Jana Duggar the "Cinderella" of the Duggar clan for not following their expectations of marrying young and having babies.

Now, on the heels of Jana's twin brother John David announcing his courtship, RadarOnline.com has exclusively learned there's one big reason the Counting On star has stayed far away from potential suitors.

A source close to the reality star revealed to RadarOnline.com that Jana, 28, has never publicly entered a courtship because she doesn't want to be anything like her younger sisters!

"Jana doesn't want to be like a lot of others that just go out and get married and end up in a relationship that is negative," the insider told RadarOnline.com.

As RadarOnline.com readers know, growing up as a Duggar woman comes with a long list of rules. Jim Bob and Michelle Duggar instructed their daughters to wear modest clothing so they would not seduce men. The Duggar girls have also reportedly been banned from befriending any other women who had children out of wedlock.

The source added that Jana – who has never publicly announced a courtship – is happy being alone.

"She's content with whatever the Lord wants for her," the source continued.

Although the source said Jana is following her instincts, even Jim Bob doesn't approve of her single status. Earlier this year, the Duggar patriarch snubbed Jana on her own birthday, joking to a church crowd that she was "still praying" to meet someone.

Then last month Duggar fans felt sorry for Jana who appeared as the family's outcast as she tended to fruits and veggies in the family's garden while the rest of her siblings were busy announcing courtships and welcoming new babies into the world.

The source said that the TLC star is also "not" homosexual – a claim that has plagued the oldest Duggar daughter for years.

Instead, Jana daughter simply does not want to rush love.
