Its all projection MW. Its what they do isn't it. Takes the heat off their own behaviour if they can turn it around on you.
You know exactly what he is and you know that whatever he has said about you was just cruel and hurtful, to justify his own behaviour. The drugs and alcohol have probably addled his brain, so whatever he has thought or said about you should be totally disregarded for that reason alone. Boo hoo that you didn't let him continue to be a druggy dad, how unfair.
I'm sure my H thought I was controlling for trying to insist he spend time with his DCs and me on his rare weekends off, rather than letting him use all his free time to go off on his own running or pottering in the garage, or hiding in the office.
He can see that as me being selfish, wanting to tie him down etc. but I know full well that I was trying to get him to see how important his involvement was to us all, so that the DCs had the family life they deserved.
Now I've given up trying, all of a sudden he 'gets it' - just so contrary and immature really. They all just sound like lost little boys who have never accepted the responsibility of family life and don't see why they should have to man-up and be an adult. Mid-life crisis is such a joke, but it seems to be happening all around us.
