How to Move On?

Nothing can keep you from a happier future than a lingering relationship wound. We’ve all been there: Experiencing good love gone bad is painful. It doesn’t really matter what the circumstances were, or who was right and who was wrong. The bottom line is that it hurts and that the pain is preventing you from moving forward. While time is the best healer, there are 5 concrete steps you can take that will facilitate the process:

1. Cut of Contact, it is doesn't mean to unfriend him. It just limit your interaction, so slowly you can forget him and get use to be friend with kindness and respect with your ex.
2. Let go off the Fantasy, Many people don’t realize that a large majority of the pain they experience during a break-up has nothing to do with the relationship they really had. Relationships always end for a reason. It is rarely a complete surprise because things generally haven’t been going well for a while. Because our mind is trying to heal our heart, the painful memories often get shifted to the background and we find ourselves remembering and longing for the good times. The point here is to remember the full truth of why the relationship ended. Eventually, letting go of these events will be an important part of the forgiveness and healing process, but in order to let go of something you must first acknowledge and accept that it happened.
3. Make peace with the past, Learning to forgive and make peace with things that happened in the past can happen more easily when you take your focus off of the specific events that occurred and instead try to see the perspective of the people involved. Seeing someone else’s perspective can help you understand the events that unfolded better and make them less personal. It can also be easier to forgive someone when you see them as a whole person. If you find yourself stewing in anger over something that someone else did or didn’t do, try to pull back and remember the good qualities you saw in them when you first met, and recognize that we all have flaws and we all make mistakes.
4. Know it is okay to still love them, Love is never wrong. There are many forms of love, and it has the capacity to shift, evolve, and change over time. Let the romantic love you felt evolve into a different type of love that encompasses caring and compassion for a person who had an important place in your life. This will help facilitate the healing process. A good deal of the pain we feel when a relationship ends has to do with the loss we perceive. 
5. Love yourself more, Self-forgiveness is an important part of self-love. In hindsight, you may feel that there are things you could have done differently, but it is impossible to know what different outcomes could have been. Blaming yourself in a self-reproaching way is a futile waste of energy that only brings about negative emotions and delays the healing process. Love yourself then you can love others well.
