NC Rage?

Been no contact for 3 months. All means of communication are blocked. Today a mutual friend tells me that he has been posting comments and such about "people who are flakes" and "not big on their word" on FB. I know it is better that friends don't tell me these things and I have mentioned it to them in the past to refrain from doing so. But the co-dependent in me can't help but feel upset thinking that comment was directed at me??? I know I shouldn't care what other's think or say and I shouldn't defend myself either.

Is it common for them to rage during no contact? Was he trying to trigger me to react? I don't understand these people. Why try to provoke someone after all this time? So much for being civil!
