Coercive control is a pattern of behavior used by an individual to dominate, manipulate, and intimidate another person in a relationship. It's characterized by a wide range of tactics aimed at undermining the victim's autonomy, self-esteem, and freedom. This can include psychological manipulation, isolation from friends and family, financial control, and threats of violence. Coercive controllers often exert their power gradually, making it difficult for the victim to recognize the extent of the abuse until it becomes pervasive and overwhelming. It's a form of domestic abuse that leaves lasting emotional and psychological scars, often trapping victims in a cycle of fear and dependence.

Post-separation abuse refers to the continuation of abusive behaviors by a perpetrator against their former partner after the relationship has ended. This form of abuse can take various forms, including harassment, stalking, threats, manipulation, and even physical violence. Perpetrators may use post-separation abuse as a means to maintain control over their former partner, punish them for leaving the relationship, or prevent them from moving on with their lives. It can have severe psychological and emotional impacts on survivors, leaving them feeling unsafe and constantly on edge. 

Parental alienation is a complex psychological phenomenon where one parent manipulates a child to reject the other parent, often during or after a divorce or separation although parents can effectively use alienating tactics in intact families. This manipulation can take various forms, including denigrating the other parent, limiting contact between the child and the targeted parent, or falsely accusing the targeted parent of abuse. As a result, the child may develop unjustified feelings of fear, anger, or hostility towards the targeted parent. Parental alienation can have serious and long-lasting consequences for the child's relationship with both parents, as well as their emotional well-being and development. It is a challenging issue that requires careful intervention and support to address and mitigate its harmful effects on families.
