Although they often prefer to be footloose and fancy free, once involved in a relationship Sagittarians will make it as much fun and as enjoyable as possible.

Sagittarians are usually very gregarious people, but they gladly find the time for one important loving relationship. They are very warm and caring, although their light-hearted affections may seem a bit too casual for some of the more passionate Sun signs, who prefer more security.

The Chase
As the hunters of the zodiac, there is nothing Sagittarians like better than the thrill of the romantic chase. However, some of them lose interest once they have captured the heart of the person they have been pursuing, and will then set their sights on someone new.

Freedom
Independence is vital to Sagittarians, who can quickly start to feel trapped in a suffocating relationship. Some of them expect their partners to wait around while they pursue their own interests; and their tendency to blow hot and cold can be very confusing. They usually possess suitably warm emotions and also a wonderful zest for life which is often filled with endless absorbing interests. Naturally optimistic, they will always tend to shrug off defeat.

Casual Romanic
Sagittarians may plunge into a love affair whole-heartedly, but do not commit themselves too easily. They enjoy the chase of a new romance and often prefer censual relationships to something more permanent which denies them freedom.

射手座感情奔放，富有爱心，喜欢快乐、有情趣的爱情体验；热中于群体活动，独立，喜欢自由自在，只是对爱情的态度有时显得过于轻松不经意；喜欢追求时的刺激，兴趣失去得也快，于是重又寻找目标；天生的乐观派，永远不怕失败；追求自由，不喜欢在另人窒息的关系中忍受，不愿被束缚。
