“Finally, we emphasize that no person is expected to stay in an abusive marriage. Some abused women believe that church teaching on the permanence of marriage requires them to stay in an abusive relationship. They may hesitate to seek a separation or divorce. They may fear that they cannot re-marry in the Church. Violence and abuse, not divorce, break up a marriage. We encourage abused persons who have divorced to investigate the possibility of seeking an annulment. An annulment, which determines that the marriage bond is not valid, can frequently open the door to healing.”

THE EFFECTS OF MARRIAGE
Can. 1134 From a valid marriage there arises between the spouses a bond which by its nature is perpetual and exclusive. Moreover, a special sacrament strengthens and, as it were, consecrates the spouses in a Christian marriage for the duties and dignity of their state.
Can. 1135 Each spouse has an equal duty and right to those things which belong to the partnership of conjugal life.
SEPARATION WITH THE BOND REMAINING
Can. 1153 §1. If either of the spouses causes grave mental or physical danger to the other spouse or to the offspring or otherwise renders common life too diYcult, that spouse gives the other a legitimate cause for leaving, either by decree of the local ordinary or even on his or her own authority if there is danger in delay.
Can. 1154 After the separation of the spouses has taken place, the adequate support and education of the children must always be suitably provided.
Can. 1095 The following are incapable of contracting marriage:
1/ those who lack the sufficient use of reason;
2/ those who suffer from a grave defect of discretion of judgment concerning the essential matrimonial rights and duties mutually to be handed over and accepted;
3/ those who are not able to assume the essential obligations of marriage for causes of a psychic nature
