Intimate relationship
Social support

Social support from an intimate partner is beneficial for coping with stress and significant life events. Having a close relationship with someone who is perceived as responsive and validating helps to alleviate the negative impact of stress, and shared activities with an intimate partner aids in regulating emotions associated with stressful experiences. Support for positive experiences can also improve relationship quality and increase shared positive emotions between people. When a person responds actively and constructively to their partner sharing good news (a process called "capitalization"), well-being for both individuals increases.
