Face it, marriages can be very difficult at times, sometimes you wonder how to mend a marriage and even if you made the right decision. But understand there are no perfect marriages, every married couple has their time. Arguments and fights will happen, it can not be avoided so do not think you are alone with this. What makes a great marriage is how a couple handles those bad times and avoid copying with the break up of marriage.
You need to have both of the couple committed to making it work. One of the couple can do what they can on their own, but if both husband and wife work together at it you can make the marriage work. If only one of the couple is willing to make an effort to save it, then consider if the marriage is worth saving. If the partner is not willing to help what are they thinking?
Do not blame each other for problems that arise, the process of mending a marriage is not about winning or who comes out ahead. Both of the couple should get equal time to express their feelings and the other needs to listen, without arguing their side or point of view.
Do not forget what it was that bought the two of you together in the first place. Go back to that time and you will see how nice you were to each other. Did you loose that somewhere along he way? Try to be nice now, it could be doing little things for each other every now and then which can go a long way.
