How to save my marriage after an affair. Are you among the many wanting to find out the answer to this? Read on. Saving your marriage after an affair is actually possible in some cases, provided that the person that had the affair (or the offending party) is remorseful, and the person that was offended is forgiving. Forgiveness is among the most important things in life, because it opens doors to many good possibilities. However, there are times wherein the offending party (this being the person that cheated) is a repeat offender. In such cases – even if this happens to be you – then ask yourself if it is really best for your spouse to stay with you, even though you know you are struggling to stay loyal to him or her. Just the same, it is possible for people to change, and if you know that you have it in you to do this, you can talk to your wife or husband about it.
