The success of a relationship depends on many factors - character, level of attraction, external circumstances and others. But we also can't ignore astrology, according to which there are 4 zodiac signs which have a tendency for serious relationships. If your partner is one of these signs, rest assured that they'll be with you forever.
Libra
They only begin a relationship with someone whom they've long been friends with before. Once they've given their heart, they are fully devoted to their partner. Libras are extremely romantic and love to make surprises. They don't cheat but they don't avoid innocent flirting either. There's only one way you can lose them - if you see them as a given or don't invest the required care in the relationship.
This is the most loyal relationship possible. They can be with a single person from elementary school until the end of their life. For them, relations with their partner are something sacred and they defend them tooth and nail. But there's a catch - if a Pisces feels unappreciated and misunderstood, they have a tendency for cheating. And would never admit it either.
Stay-at-home types by nature, the most valuable thing for Cancer in the world is family. They can forgive absolutely everything, although this does not at all mean that they're not going to nag you about it for the rest of your life. The only way to drive away a representative of Cancer is if they feel that your feelings toward them have gone cold. That which kills them on the inside is when someone doesn't show them the care and love they so need.
Taurus is loyal and practical in every sense - he never jumps from one relationship into another. Representatives of this sign often remain single for a long time, since they prefer to choose just as long, until they find the right partner. That which can lead them to give up on even the most special person is the absence of passion in the bedroom.
