I am glad your break is going well.

Yes . Self care is a priority and if you need to delete her messages to help not dwell on them, that is a good action.

You are right in your assessment of her, but that is only the part that is missing. Focus on the good points.
1 she wants to reconnect with your girls.
2 she wants you on her team. (This is a debatable topic but for now consider it as positive)
3 she admitted she was wrong.
4 she illuded to putting girls before current bf
5 she is contacting you a lot and apparently hidding if from bf
6 she wants you to be happy.
7 she is in therapy to help her move forward.
8 om, moving out etc have not made her happy.
9 she realises your M was good and she was wrong to say otherwise
10 she acknowledges how good a dad you are.
11 she realised she has still a void and isn't trying to artificially fill it.

That is just off the top of my head. There are surely more. I am not asking you to do anything different. Continue as you are but I think it would do you better not to dwell on what is missing and appreciate/acknowledge what is positive. You are right to be cautious. Definitely.

Best wishes
