What leads to infidelity? the most common cause of infidelity is a sense of emotional disconnection from your partner and not keeping the spark alive. The person who has committed infidelity complains of feeling unappreciated, unloved, ignored and overall sadness or feeling or insecurity which led them to cheat on their partner. 

Couples will cite countless reasons for their fire dying. Usually, these reasons center around not having enough time to spend together and slowly losing that connection they both treasured. That might be because of long distance, seemingly incompatible work schedules or simply growing responsibilities like dealing with children and their needs. What might have been a temporary state of disconnection unconsciously becomes habit. The priority for spending time together shifts from “tomorrow” or “next week” to “when things are settled” and eventually fades into “never.”
