"Break ups"

Well, when i break someone, I have many ways of reacting depending on how much you loved that person so that I explain each reaction according to the degree of importance:
When the importance is low, I start a friendship with that person, as if nothing had happened, even improves our relationship.
When the importance is regular is a bit more difficult see that person as a friend, but with some time it is possible.
When the importance is much, I think it is more difficult, because the experiences lived with that person do not forget so easy,
but still I think it is always possible and well.
