NOTE :- This post is purely for entertainment purposes, none of you should base your relationships on this analysis. Love can find anyone at any place and it is always beautiful.
5) Libra and Capricorn
Libras tend to be trusting, which could lead to a Capricorn manipulating them to get what the want. These two signs are just better off with other people simply because the relationship would never exactly be relationship. One would be extremely clever and the other would just be too innocent, if this were to become prominent in any way to the Libra then things could really take a turn for the worse.
4) Gemini and scorpio
Scorpios want to have a deep connection with a single person while Geminis tend to be more superficial with a larger group of friends. In the end, neither person will get what the want from this relationship. One does not really care about public opinion and to the other it truly matters, it's gonna be tough.
3) Taurus and leo
Leos are extroverts while a Taurus usually tends to keep to his or her self. Eventually this will lead to conflict in the relationship because one might force the other to face a kind of public bonding and mingling that the other just isn't comfortable with. This might cause a usually stubborn Taurus to develop ego issues and cause further trouble.
2) Pisces and virgo
Pisces are dreamers while Virgos are very practical. Practicality and passion do not usually gel together. Practicality from the Virgo's end may cause a Pisces to either focus more on achieving it's dream or lose all ambition altogether. Either way, it may lead to interpersonal depression among the two.
1) Scorpio and aries
Both of these signs are independent people who may ultimately be too independent for one another. Scorpios tend to be jealous while Aries tend to be flirtatious, leading to inevitable problems. They say that an excess of everything is bad, being overly independent isn't really all that amazing either.
