Relationships can be complicated for many people, so you've probably heard the phrase, "I'm better off alone."
This can be true, especially if the people saying it are one of these signs:
Virgo
A Virgo has so many things to do and plans to accomplish that she will most likely enjoy the ease of being single.
Without a relationship to worry about, it's much easier for them to accomplish all their goals.
People of this sign are busy waking up early and going about their activities. They don't have time to stay up late whispering romantic words in their partner's ears. Not to mention the fact that they are so selective about their partners that no one is "good enough".
Sagittarius
For an adventurer like Sagittarius, a relationship isn't always the best option. This does not mean that they are not romantic, they are just such a "free spirit" that it is difficult for them to make compromises for the sake of a relationship.
They prefer to meet many people and travel to the farthest corners of the world.
Aquarius
Instead of worrying about how they might fit into someone else's world, Aquarius worries more about how a potential partner might fit into theirs. An Aquarian is so individualistic, true to himself and irreplaceable that he wouldn't change a thing for anyone. He never rushes into a relationship, because after all, he is very happy even alone.
