Antifriend 

A friend who lacks the qualities of an idealistic friend. Not to be confused with a frenemy which is more of a love/hate relationship. May have been a close friend at one point. In many ways they are fiercely independent or distant for personal reasons, which creates an air of tension. But, that tension is never redeemed, so they are especially prone to becoming the black sheep of a group.

We tried reconnecting as friends but it's not the same, I guess he's an antifriend now.
