Double breakup

When someone, after breaking up with you but promising that the two of you will stay friends, breaks contact completely and decides they no longer want to even be friends.

The double breakup goes something like this.

Mikey: "Hey I don't want to be in a relationship with you anymore, but I care about you and I want to be friends."

Not long after....

Mikey: "I don't want to be friends anymore, either."
