There are several reasons why women may stay in abusive relationships.
Love and addiction
Many women may have strong feelings for their partner and hope that he will change or that their love can overcome all difficulties.
Low self-esteem
Women with low self-esteem may feel that they deserve to be treated poorly and are unable to find someone better.

Fear of loneliness
Some women are afraid of being alone and believe that it is better to have any kind of partner than no one.
Lack of support
If a woman's family, friends, or community do not support her or see the problem, she may feel isolated and helpless.
Social stereotypes
Social stereotypes can instill in women that their main role is to be a wife and mother, and they must endure everything to preserve the family.
Childhood trauma
Women who have experienced childhood trauma may unconsciously choose abusers because their previous experiences may lead them to believe that such treatment is normal.
Mental disorders
Depression, anxiety disorders, or post-traumatic stress disorder can make it difficult for women to assess their situation and choose safe relationships.
Material dependence
Women may fear losing financial support or housing if they decide to leave an abusive relationship.
Lack of information
Many women lack knowledge about what a healthy relationship looks like, how to deal with abuse, or where to seek help.
Cultural and religious factors
In some cultures and religions, it is considered normal for a man to have power over a woman, and women are taught that they must submit and endure violence.
