#2 Pisces

Pisces gives their partner their undivided attention and demands the same in return. When they fall in love, they get too attached and make a point of stalking the person, going so far as to make notes of their whereabouts. According to astrology, Pisces is among the clingiest signs and can become extremely needy when they fall in love.

The sign of Pisces symbolizes co-dependency. Even though their generosity is misunderstood, some people enjoy giving and thrive on the pleasure it offers them.

If you screw over, they will tend to give you some of the most third chances or even more second chances. 

They are so altruistic that they will go above and beyond to help others. If you mess up, they will grant you a second or third chance. They need a partner to share their accomplishments with, someone to appreciate them and make them feel cherished.

They want someone who will cherish them, who will always be there for them, and with whom they can have in-depth conversations. They will take extra precautions to prevent their relationships from collapsing if they see any changes in them or if they think their partner is getting bored with them.
