this might sound bad, but don't forget him, and especially don't forget why you split.
sometimes you have to remember the bad they've done to get over them, to see where you made a mistake. don't miss understand that please.
whenever two people split up, there is more than one side of the story and all sides of the story have a problem or and answer.
look back and see if maybe you shouldn't have started dating him to start with.
aniline your relationship with him as if it was someone Else's, someone you didn't want hurt and as if it's someone you wanted to help get out of the relationship.
we can be our own biggest help sometimes. and our own worse nightmare
