I'd trust your daughter's instinct. She's 8 years old and afraid to be with him without you around. There is a reason for that. Trust her.
And I agree, it is not up to you to pay anything and why do it. He created the problem, he can find the solution.
Please remember that "we" are not the answer to any of their problems, we are not even a good option. "We" are not the solution. It's okay to take care of ourselves.
