Horoscope- Who are you compatable with??

Conflict or compatability??
I was never one to believe in horoscopes and who im compatable with however recently i have been reaseraching into it and have found it very interesting. Being a libra i have discovered that i am one of great gentleness and like sharing, somebody who gets along with everybody.
i'm entrigued to know how people are able to understand so much about someone just beacuse of the month they are born in.
Aries
Taurus
Gemini
Cancer
Leo
Virgo
Libra
Scorpio
Sagittarius
Capricorn
Aquarius
Pisces
There are 12 signs for the 12 different months in the year. Daily horoscopes are available in the newspaper or online, people are able to gain an insight of there day or week ahead. Is this a good or bad thing? Can we become dependant on horoscopes to help us pan out our lives. For example if your single your star sign is able to suggest when and how you will meet someone, so it can be considered to be looking into the future in a way. So you wait for this day to come around so you can meet you future husband/wife.But what if it never comes?
I dont know it can get so confusing you go online and you look at your star sign and your able to see who ur compatable with, who your not compatable with, who makes a good friend in the horoscope world, i mean it can pretty much take over your life and i can understand why people become obsessed with it.
