Counting On fans have been following the life of Jana Duggar, especially her romance. Among the siblings, she remains single at 29 years old. Since some of her sisters got married at an early age, theories are spreading as to why she is not yet tying the knot or even looking for the perfect guy for her.

Fans believe Jana is not yet getting married because she is too important to the household. She seems to be the obedient type, who is following the rules with no complaints. With her personality and birth order, she is the one looking after her younger siblings.

She also has a lot of responsibilities for the family. Janna seems to be running the entire household on her own. According to the Cheat Sheet, she is so important to the Duggar household to be lost to marriage.

If she leaves, there will be no single Duggar girl over 13 years old. Although 13 is quite old enough to do household responsibilities, it is not old enough to run the entire household.

Counting On fans also claim Jana remains single because her parents, Jim Bob and Michelle Duggar, need a full-time nanny. She is, allegedly, forced to live at their ancestral home to look after her younger siblings.

However, there is no evidence to prove this claim. The Duggar women have been not allowed to move out of their house until they get married. Hence, as Jana still lives with her parents, some believe her family is trying to prevent her from living her own life.

Meanwhile, the most popular theory of them all is Jana could be gay. Her single status may have something to do with her sexuality, and she is only unable to come out because of her family's beliefs, per Celebrity Insider.

The Duggars have been known for being too conservative. They are openly against gay marriage; so, having a gay family member will never fit the family brand.

Jana is believed to be gay because of her closeness to Laura DeMasie. They are incredibly close and even appear on each other's social media profiles often. Laura has also joined the Duggar family's vacations and even lived with Jana at their Arkansas' home.

Laura has moved to Georgia, and the Duggar family has tried to shut down the rumors about Jana's sexuality. However, it seems like no one is convinced that the two's friendship is platonic. Counting On fans may continue to make their theories about Jana's single status until she gets married.
