well i have found when he pops into my head, i feel the same way as i would if i bumped into him in a bar, and i automatically think "oh god, not you, just bugger off, i cant be arsed with this now".
It still happens 100 times a day, but im hoping it will ease up as my mind is automatically fed up every time he raises his ugly cheating lying head.
the songs definitely don't affect me any more, or films or even hearing his name. songs on the radio, movies etc, are all my life, and he doesnt get to belong in it anymore. i also sing the songs loudly to help, they're mine, not his. he can bugger off when he rears when his head in the middle of a good song.
