Answer 1

Confidence
People may have confidence in other people or forces beyond their control. For instance, one might have confidence in the police to protect them, or may have confidence that a sports team will win a game. Faith and Trust are synonyms of confidence when used in this sense.

Usually when someone is referred to as 'confident' they are referring to self-confidence. Self-confidence is faith in one's own abilities. People with high self-confidence typically have little fear of the unknown, are able to stand up for what they believe in, and have the courage to risk embarrassment (for instance, by giving a presentation to a large group of people). One who is self-confident is not necessarily loud, brash, or reckless.

Infidelity is literally a breach of faith. Fidelity, derived from the Latin word for faithfullness, is the principle of not deceiving one capable of being deceived. Infidelity is a breach of good faith that applies in a number of contexts. In the context of this article about close relationships, infidelity is referred to as cheating, which is 'any violation of the mutually agreed-upon rules or boundaries of a relationship'. It does not require sexual behaviour to qualify as infidelity. The definition of what constitutes an act of infidelity varies between and within cultures. People in a close relationship may have very different ideas and perceptions of infidelity - see Blumstein. A man cheated by his wife is referred to as a Cuckold but no equivalent word exists for a woman cheated by her partner.

In this article fidelity also refers to the accuracy and integrity of self-representation, honesty or candor in an intimate, committed relationship. Integrity may be defined as 'the inner sense of wholeness deriving from honesty and consistent uprightness of character.' Infidelity is a breach of that integrity through the use of deception by one party to a committed relationship and not necessarily monogamous. This breach is experienced as a betrayal of an explicit or implicit agreement between the partners to not keep secret those matters now the subject of deception. 'Deception is the covert manipulation of perception to alter thoughts, feeling, or beliefs.'
