Why he needs to make sure she knows he’s 100% clean and spinning it so he looks like the victim and the hero.
'Victim' and 'hero' are story-telling elements. Telling ourselves (and others) stories about why things happened and what they mean for the future is part of how all humans tend to make sense of life.
Stories may be solidly based on facts (true stories) or may be invented (fictions). Sometimes it's a bit of both.
Your ex is telling himself (and your daughter) a story about how he was a 'victim' of mummy and the judge conspiring against him to deny him contact and a 'hero' for doing the courses so he could regain contact because he missed her. From the outside, this is obviously all a bit grandiose, and while he deserves some credit for doing the courses instead of ditching his daughter forever (it happens), he's hardly the hero he's making himself out to be, and you're not the witch he's making you out to be.
The relevant facts in this matter are that
- You did take him to court to restrict contact because you felt unsafe with the way he was behaving
- The judge decided that your ex needed to take time out to learn some new behaviours
- Daddy did what he was ordered to do and now he can have contact again
You can feel confident reiterating these facts to your daughter, and correcting any outright distortions on your ex's part, but don't be tempted to stray into storytelling of your own.
Because you are also telling yourself a story, which is that your ex's new 'Disney Dad' persona is a complete put-on, that your daughter is going to be taken in by his version of events, he's going to steal her away and you will lose her forever. In this way you are actually also telling yourself a 'victim' story, with you and her the 'victims' and him some kind of all-powerful sorcerer who can bewitch your daughter with his words and cheat you of your relationship with her.
You're giving him a lot of power with this story! Yes, your daughter may seem sorry for her dad now; all people feel sorry for victims. But she also seems sharp enough to spot some of the distortions and 'fake rules' in his home. She's only little now and she will learn to see things clearly over time. Give your own daughter some more credit for being capable of learning how to discern fact from fiction!
And in the meantime if you want a good story to enjoy and talk about with your daughter, try The Wizard of Oz. It's all about how we find our own strengths inside us when we have to face scary challenges, and that sometimes people who pretend to be Great and Powerful are actually just scared ordinary people who have created a big impressive illusion to hide behind.
