Trust that everything you tell them will be kept strictly between the two of you, so you can feel at ease venting and talking things out with each other. Communication that is honest and open is a sign of a good relationship with a solid link. The trust and confidence you have in one another is what defines a strong bond between people in a relationship. It allows for there to be no secrets between two individuals, which in turn makes for a more stable connection. Being able to rely on your partner to be honest with you and to have your back when needed are all signs of a strong bond. In modern times, this trust is sometimes replaced by a lack of privacy. If one or both partners join a social media site like Facebook, it creates a public space where they can share information that might not be appropriate for discussion in front of others. However, communication is still important even within these online circles and having an open line of contact provides support when it is needed most. This type of bond is useful because it allows for changes to be made if necessary. Some relationships may exist solely due to necessity rather than choice. For example, friends with benefits or roommates would not usually be considered bonds but rather arrangements had nothing else been available. However, they do share similarities with true partnerships in that they both provide support when needed and don't involve any commitment beyond the current situation.
