1, even if u are their son or daughter u have no say on how they spend their money or how they can solve it too... I say this cause ur mom and dad have their own agenda and if you side with one and say smtn... u will regret it ... cause you might even ignite their divorce... even more... but if I were in ur shoes.... whenever ur dad say something bad about ur mom try to compromise and tell him the good things about her that he keeps on missing... also tell hem what u admire about her... also do the same with ur mother... be the reason for their love not for their doom.
