ExH hurting the people I love

[VoodooPinsNeeded]

Divorced 10 years ago, I took 99% of the responsibility for our DD and his elderly DM and have brilliant relationships with both. He sees them very rarely and upsets them both frequently with his thoughtlessness.

He's acting like a teenager and I'm left to deal with the trials and tribulations of the family he left behind. I wouldn't be without them and love them both dearly and am actually quite grateful that I don't have to deal with him as well any more.

As much as I want to track him down and shake him, I can't and won't get involved but AIBU to make a voodoo doll of him and stick pins in it?

Karma! I truly believe in it.. my first husband cheated on me after 12 years together and our child was 1 year old.. he left me for her... we had been together scince being 16 ( first loves) .. l had a breakdown. he married the other woman...12 years later she cheated on him and left him... . He actually rang me out of the blue to say sorry for what he had put me through .. because he was now going through the same... no Voodoo doll needed.

What is this post about @VoodooPinsNeeded ?

Just feeling frustrated that despite being NC with ExH he's still upsetting me by upsetting the people I care about when he obviously doesn't.
There's nothing I can do to fix it except show them love + support, which is what I do, and hope that @ItsFridayIminLoveJS is right about karma!

I am hoping that either my ex cheats on the new wife or she cheats on him. I would prefer him to do it cause then he would feel the hurt he caused me.
