So he removed your DD and then you left the country without her?
On some level I agree with swing you left when you potentially had a choice not to. I absolutely understand that you felt at the time you had no choice, but you did choose to leave without your DD and the courts are not likely to look favourably on that.
Also does your ex have other children? Because this may also go in his favour.
I know for instance of one person who wanted to leave to be with her new DH in another country. She and he did not have children together, but her child’s ex did have children with his new partner, so making them an existing family, iyswim.
At the time she had full residency of the child, but the courts awarded residency to her ex with her having holiday contact only where he could travel to her country of residence. She left to be with her h, and now the son will be living with her ex permanently since the courts considered that she had prioritised her new living arrangements over her child when moving abroad.
I understand that at the time you feel you made the right decision for you, but it’s not the right decision for your DD. Especially as you have waived any contact in favour of living abroad. Given you are only seeing her every few months at best, this contact is unlikely to be increased given her age.
To the courts being settled with the dad is no different to being settled with the mum. And as things currently stand she is settled with her dad.
