The intensity and passion of Scorpios makes them unforgettable partners when it comes to love. They take their love affairs very seriously, which sometimes leads to jealousy. Their innate secrecy can also make it difficult for them to confront problems in a romantic relationship.

Passion
There is no mistaking it when Scorpios really fall for someone because they pull out all the stops. Once they are deeply involved in a relationship, they show just how passionate they can be. When love comes their way, they are convinced that this is the relationship that they have always been waiting for, and will invest in it all their energies. Scorpios are very suspicious, and can easily work themselves up into a state of jealousy if they imagine that their other half is being untruthful. They will soon gather up the evidence and challenge their loved one. This is when the volcanic Scorpio temper can emerge, often with very frightening results.

Intensity
Renowned for being introverted and intense, Scorpios bury their deepest emotions well under the surface and positively relish their resulting mysterious image. They are very faithful and need the security of permanent relationships. If they are badly let down in a love affair, they may decide to play tit for tat. 

Possessive Mate
They may be cool on the surface, but underneath Scorpios are intensely passionate, both physically and emotionally. When love is sweet, they are very loyal, but when things go wrong they may show a sting in their tail.

天蝎座内敛，热情，把最深沉的情感隐藏于心，有种神秘感；对待爱情严肃认真，一旦坠入爱河，便会全力以赴；绝对忠诚，需要持久的关系带来的安全感；多疑，嫉妒，若在爱情中失望，很可能会一报还一报；火山一样的脾气一旦爆发，通常会带来可怕的后果。
