Infidelity—also referred to as cheating or adultery—describes the act of engaging in emotional or sexual intimacy with someone outside the agreed-upon boundaries of your marriage or relationship. Infidelity may or may not involve sexual encounters, and can happen in person or online. It  can have serious impacts on relationships and on the individuals involved, including those who are cheated on, and those who do the cheating. When infidelity impacts a relationship, it can leave the people in it feeling highly distressed, depressed, and out of sorts. It can cause heightened anxiety, suicidal ideation, and signs of post-traumatic stress disorder (PTSD). Learn more about your ad choices. Visit megaphone.fm/adchoices
