1) Fear

Fear is a powerful motivator. Fear of retribution, fear of being alone, fear of an unknown world - all of these play a part.

Many times the abused woman has been so beaten down - by both her spouse and life - that she has very little ability to envision a life outside of the relationship.

2) Low Self-Esteem

It's not surprising to think that after literally years of being degraded, a woman's self-esteem might begin to erode, right? Many abused women have absolutely zero confidence in their ability to take care of themselves, no matter how unrealistic that lack of faith may be.

3) External Impact

Another big concern of abused women when considering leaving the relationship is the impact that decision will have on others, particularly their children. Many times there are also social and business implications, or repercussions for extended family.

Although to an outsider, these may seem like petty concerns, to the victim they are the very fabric that her life is built upon.

It's a horribly complex situation, and if you are the friend of an abuse victim, the best thing you can do is to simply let her know that you are there for her - whether she stays or goes.
