A couple's separation is traumatic. During separation, a woman leaving the father of her children experiences guilt, fear, relief and resentment, according to the article "Psychological and Emotional Aspects of Divorce," on Mediate.com. The breakdown of a marriage happens over months and years, not overnight. In order to move past guilt, examine the relationship. Time, self-healing and space offer perspective and alleviate guilt.

Avoid obsessing over guilt. You can always find reason to feel guilty: the time the children will not spend with their father, the lost relationship, the financial change the family may endure, according to "Coping With Guilt as a Single Parent," by Cynthia Yates, author of the book, "Living Well as a Single Mom: A Practical Guide to Managing Your Money, Your Kids and Your Personal Life." Don't dwell upon guilt or internalize it into a negative inner dialogue. Relationships end for a reason and eventually everyone heals and moves forward.

A mother's guilt over the loss of the family unit can have a lasting effect on her child. Children move forward if they know their parents have resolved feelings regarding the divorce, according to "Children and Separation," a Family Relationships Online article. When parents move on, so will the children. Counseling may be necessary if the mother cannot move forward.

Guilt is sometimes accompanied by fear and anger. No matter how angry a mother becomes, she should resist the temptation to bad mouth the child's father. The breakdown of the parental relationship does not change the fact that he is the child's father. A child should be kept out of arguments between adults, advises the article, "Helping Children When Parents Separate," by The Child Center and Adult Services, Inc. When parents bad mouth one another, children become resentful toward them.
