Get him back forever
Sometimes having an ugly breakage is inevitable. We say things that we did not really say when we are filled with emotions of anger and that applies to things we do as well. Before you even ask "how to get my ex back", one thing you have to evaluate is how and why you ended the relationship. Also, it is important to remember that once you are able to fix things, you should never put the past again and yes learn to forgive and forget is the only way you can do this. This may not be possible especially if the pain it caused you to support you too. Although it is almost desperate for some, if you really want your relationship to work, you will do everything to save him.
One way on how to forgive and forget, it's finally out of the meaning of letting all your emotions out and deal with the problem head on. Tell your partner that you all this trouble, it's okay to cry. You need every bit of anger coming from your chest. Release your anger and if the other person apologizes, he agrees, but only if he or she is sincere. You have to sit and talk. Of course you do not expect everything to be okay in a few days, give yourself a little time to finally let go of your grudges. In my case, it took six months before finally forgave my boyfriend so completely and now it feels like the bad thing never happened at all because I chose to forget too.
Forgiveness is not the easiest to give a person who has caused you much pain and tears, but if you really like the person you will find a way to forgive him. Every time you argue, do not raise her past mistakes. It is very important to resolve this first before you even consider "get him back forever"
