Though there are exceptions, we here have tried to take into account the personality traits that are unique to the signs and from there tried to find possible reasons for fear in the spheres of attachment, romantic intimacy and relationships.
So here it goes.
Aries (March 21st-April 19th)
They are really fiery in their passions. When they obsess over a particular person romantically, they do it ardently. Their greatest fear is their same passionate intensity backfiring; that is their passion not being reciprocated and in turn appearing to be just an overbearing personality.
They get attached with difficulty but when they do, it’s nigh impossible to shake them from their resolve. And hence, they never want to be the one to break the relationship up.
They don’t want to choke you up, and no matter what it appears to be, they just want to protect you; from EVERYTHING. But their execution of this protection is often times known to be problematic with frequent usage of the phrase “I am protecting you from myself (by breaking up)”; hence proceed prepared.
Taurus (April 20th- May 21st)
Now, this is another of the problematic signs; like bulls in a fighting pen, they are focussed when they are in love. Thing is, the stage before is the icky one. They are VERY independent and career-oriented people, with concern ONLY for material gains.
Their greatest fear would be of the effect their romantic other has on their chalked out perfect lives and goals. Now I don’t know if this is consolation enough or not, (and this is true for Aries as well) once you two are a couple, even if you don’t last, your effect will last on their lives. Once they let someone in, they stay in one way or the other.
Gemini (May 22nd-June 21st)
A Gemini is an airy sign. They spend their entire lives trying to figure out how to be around people and how to fit in.
Their greatest fear would be not knowing how to be around you and how to act appropriately. And more importantly, they are an undecided lot; if they fall for you, they WILL be confused, about everything because they will continue trying to figure out how to be around you and other people and while trying to sail in two boats, sticky situations will follow.
Cancer (June 22nd-July 22nd)
Now, this is my favorite.
They are by far the most ideal sign romance-wise, tailor-made for long-term relationships. They are committed, thoughtful, imaginative, loyal, friendly; if you end up marrying a Cancer, the only fights you’ll have will be about what you want to have for dinner; and the most likely outcome would be them agreeing with you.
Sounds perfect? There is one tiny catch. They are insecure to a morbid level. And it is mostly about how if you are happy if they are treating you well enough. This has been known to lead to a number of fights. Also, they have high expectations from romances; which causes them to commit as much as they do. If and when you do not meet these expectations, there might be episodes.
Leo (23rd July- August 22nd)
They are a proud race who values their pride and extreme rationality above everything else. Their only fear: Love itself. They are aware of the rose tinted glasses love brings as an added package and of its consequences. They know how their senses will be compromised and their pride shattered and this will invariably cause them to shy away.
Virgo (August 23rd- September 22nd)
Their greatest strength is also their greatest shortcoming: the ability to see the best in the people around them. Their personalities have something Pre-Lapserian about them, innocent and unable to process the thorns in beds of roses. As a result, they will invariably be afraid to fall in love, out of fear of betrayal; something that has been a constant in the smallest or largest of ways all their lives.
Libra (September 23rd- October 22nd)
They are all too aware of their own faults and shortcomings. They know they aren’t perfect. And this is their greatest fear as well: Ending up showing their faults to the one they love and cause disappointment. Causing someone else pain is the last thing that can enter their minds which is often driven by a strict sense of justice.
