"In the beginning," said Emmy Marie, "there was a tremendous amount of love bombing. He made me feel like he understood me better than anyone, like he loved everything about me on a deep, deep level, and I started spending all my time with him.
"After about three months, the controlling behaviors started to seep in to the relationship. It started out with little degrading comments and then over the three years ended with me feeling utterly worthless."
Marie, who lives in Portland, Oregon, is now 27 but the relationship she is describing began when she was just 15—and her controlling boyfriend was a fellow high schooler.
Her experience is not uncommon. Four in 10 women and four in 10 men have experienced at least one form of coercive control by an intimate partner, according to the National Coalition Against Domestic Violence. The NCADV also explains that "women aged 16 to 24 experience domestic violence at the highest rate of any age group, almost three times the national average."
The support group Domestic Shelters defines coercive control as "a pattern of domination, intimidation and deliberately impeding the rights of one's intimate partner." But it is not always easy to spot.
A controlled and manipulated person might not recognize that they are being abused, so they stay in the relationship. Gretchen Shaw, deputy director of the NCADV, told Newsweek last year that coercive control tactics "are harder to both explain and prove."
In some countries, including the U.K., coercive control is a criminal offense punishable with jail time. The legal position in the U.S. is more mixed. Domestic Shelters explains that in many states, coercive control laws only cover "civil matters such as child custody and protective orders," not prosecution of abusers.
