My 7th house in Libra agrees with both sides of the verdict here :-D1.) It is because she is extremely immature.
2.)It is because she's Libra lol
Let me explain!..
With my 7th in Libs I attract Libras and Libran influence like.. well alot lol My entire extended family is pretty much all Virgo or Libra with influence in their chart of whichever one they are not. I also get TON of Libras attracted to me in school and social realms. Actually, my friends and I have laughs because alot of my friends always end up in love or in serious relationships with Libra guys!
So basically there are different ways of feeling and expressing your sun sign. Some people come into life more of 'who they're suppose to be' while others come in quite obvious that their sun sign has some 'wiggle room' that they need to grow into!
A 'balanced' Libra is all the wonderful things of good judgment, faithful in partnerships, and great at balancing situations. However, an 'unbalanced' Libra is almost the opposite. Flighty indecision, unfaithful to any particular person because the need for social acclaim -and the tendency to create a lack of balance in situations so that they can then hold the 'key' to restoring balance!
I have many stories in the personal (and merely observed) archives if you need more concrete examples. It is true that most of the 'young' female Libras I know around my age bracket (late teens to early thirties) use their energies in the more underdeveloped way.
It's interesting that you posted this because, only yesterday in class, I was wanting to be fond of this cute little innocent seeming girl in class and make friends with her -but my intuition was like "NO, no, no!" and I was like 'Why not?!' and then her necklace fell out that was Libra LOL I was like (sad face) "must be an unbalanced one" LOL Maybe this post is just confirmation to staaay awaay lol. But I am so drawn to the idea of balanced Libran energy!
The guy I like now has either a Virgo or Libra Moon... let's see which it turns out to be and how that goes!
LOL about the air sign women thing -My grandmother is Libra and my aunt (her baby sister) is Gemini... my oh my. My Gemi aunt has more money and controls the family gatherings and had the 'better' husband (balanced Libra ;-) ) and all that would just send my gma a lil crazy I think lol. My gma was constantly trying to proove herself socially and status wise in this lil bubble they had -but then she would act like she was soo much more balanced and proper then my piece-of-work aunt lol. My gma finally seems to have balanced out more in old(er lol) age. My aunt mellowed more once my uncle passed. -This Gemi aunt actually has a Libra son that is IDEAL for a 'balanced' Libra male. He made me feel so secure as a young girl (he's my older cousin); I always thought a good man would have such solid judgment like him. Low-and-behold, I find out later in life I have 7th house Libra!
