The parents in Marriage Story tried. And when the mom is unable to read the things she loves about her husband, we see her hot flash of realization as she leaves the mediation without engaging in the process.
Please consider this fact: dads and moms are equally important in a child's life. Yes, there are exceptions. And these days those exceptions cut both ways. So when you are considering divorce and thinking of "going for it" because having more time with your kids would feel good to you, please consider the kids over and above your own needs. Our kids need both of us.
