Do you think she might be a good advocate for getting you the child support you deserve out of your ex? Not asking her but her realizing how unfair he has been.
I am sorry for your daughter that this isn't working out the way she had hoped. I think pretty much all kids of divorce at one time or another want their parents to get back together or at least not remarry so that is still an option.
hugs to you both, kat
