I understand justice and injustice very much. And I’ve been in all kind of situations and then some. This isn’t a situation where you could demand justice to be served. I mean you can demand but you won’t get it. You have to be realistic and not waste your energy on them.

Now if he spoke poorly of you to YOUR family and YOUR personal friends and YOUR work place, it would be a smear campaign and it would effected your life on many ways possible. In those cases you can even speak to a lawyer and have letter crafted that it must stop. He spoke poorly of you to HIS friends. And his friends are on his side. You are of no importance to them. As they should be of no importance to you

As unpleasant as it is, you cannot receive justice by trying to explain to them that he’s a jerk. You already tried. It won’t work

Where would they be pointing fingers at you and making false judgements? As long as it’s something they don’t do publicly and cause issues for you, their false judgement is their private opinions .

I mean I could tell you that you must demand justice. I could advise you to keep sending them texts and knock on their doors and approach them at events demanding they see the truth about their friend. But I won’t advise such a thing because that’s actually could be perceived as smear campaign (not saying that’s what you would do but that could be perceived as that) as it’s HIS friends.

The best revenge is living well. Focus on that. That would be the best justice. I know it sucks that they think this or that but that’s not something you can change or control so letting go and refocus is the only way
