It is completely normal for people to find it difficult to forgive and forget. One who is betrayed or hurt by other person simply can not just let it go immediately. The person who did wrong must suffer the consequences of what they did. However, sometimes, we just have to forgive and forget. This is really important especially in a relationship where situations can really go wrong that sometimes you just have to forgive and forget. Both couples should easily put everything behind them and be able to start all over again. Just remember that you need to do this willingly. If you do not forgive and forget wholeheartedly, it will be just useless.
Do not make it such a big deal
Some things are meant to be forgotten. If he or she did something wrong and it is just a minor mistake, you can just forgive and forget it already. If you learn to do this properly, you can be sure that everything will be okay for you and your partner in the long run.
By forgiving, you are essentially forgetting it. Forgiving without being able to forget is completely useless. Letting things cool off between you and your partner will make it even easier to forget. So remember, if something goes wrong, you must cool off first then talk it over.
Put it behind you
If something goes terribly wrong, you must learn to move on. You must learn to put it behind you and learn to start all over again. Retaining all these painful memories will only worsen the feeling you have so putting it all behind is one of the best ideas to completely cope with the pain.
Have a great communication
Sometimes even if your partner says he/she forgives you, it is generally important to talk it even afterwards. When your partner says he forgives you, it does not generally mean that he mean it. Sometimes, he just says that to finish off the conversation so make it a point to communicate afterwards to ensure that everything is okay.
