Infidelity Support Group
Any relationship in which one partner engages willfully in sexual relations with another outside of the partnership is considered to have experienced infidelity. This breach of trust is often traumatizing for the faithful partner as well as the relationship, and support is often needed to heal emotionally and to decide whether or not the relationship should continue after...
Low self esteem can cause self deceptions of not being good enough and fear of abandonment.
Ironically it actually causes them to hedge their bets with someone else. Sometimes the other man/woman is actually well beneath their actual spouse which seems counter intuitive.
However in this affair the cheater is empowered as she/he feels superior in this relationship and in control.
Then they feel guilty and feed the affair more to sooth themselves and get caught in a spiral.
