How can I FIX a broken long time FRIENDSHIP? and get his FORGIVENESS back ?

I think it has to be said that sometimes a friendship is meant to stay broken. Sometimes, as in any other relationship, you realize one day that the friendship was emotionally unhealthy or even emotionally abusive and you stayed in it because you didn't know how to get out of it or didn't think you really had a choice. Sometimes people are only meant to be in your life for a certain period of time and you have to recognize that the friendship may not have been a true friendship at all, or it may simply have run its course.
