Is it morally acceptable to cut off contact with a friend?

[Jack]

It's not a matter of morality but a sign of the times in which we live that the concept of friendship has changed, cheapened, and has become transitory. Facebook lists "friends" and they are often people we do not see or communicate with daily.

In your case, you must assess how long you've known this person, how frequently you come into contact (real contact, not texts, Facebook or anything electronic), and if you two have anything in common.

It's not unheard of that as you go through stages of intellectual and social development that we "outgrow" certain types of people. There is no reason to regret minimizing contact with people who's goals or personalities no longer mesh with our own.
