There really is no straight answer to this question. Suffice it to say that many other couples have gone through the same situation and have recovered and rebuilt their marriage. One important factor in rebuilding a broken marriage due to infidelity is repentance on the part of the cheating partner. If he or she is truly sorry about what has happened, then healing of the relationship can begin.
Trust and commitment are other essential factors in repairing a marriage. Both partners must commit to the process and learn to trust each other in ways that they may not have known before. With effort, hard work, and a lot of trust, things might just turn out for the better.
