What he does or doesn't do doesn't bother me anymore.
It did in the early days. I spent 5 years playing second fiddle to his 'job' read: his affairs with HOWorkers and all of a sudden he's not working 24/7.
But then I realised - he made these choices because at the time it is what he he wanted ie: to not be a part of my life or our family life - to have a secret double life. That's the part that hurts and the part I need to work through, not whatever the hell the muppet does with his life now.
Shine a light on what this brings up in you instead of focussing on what he is doing now that he wasn't before.
Why does this irk you, still?
It a rhetorical question - we all have different reasons. Mine was because I was still pissed off that he wasn't who I pretended he was. I'm still kinda pissed off about that but more at myself than at him.
The big thing he's NOT doing now that he was doing before is cheating on you. He's not cheating on you. That there is a win. The biggest of them all if you ask me.
In my situation that is worth far more than him sticking to whatever bullshit wants he carries on from his past life.
