If you have the money for the DB coach then yes, spend it. And yes, be at home when he has the girls. You need more time with him to show him you are the better option.
And you need to be as firm with the girls schedule with him as you can. And why an early dinner? Why not all night so he has no time with her for his birthday.
He still has a responsibility to these children.
I think it's time to stop sharing with OW. This has gone on long enough and you are beyond sainthood.
