looks like the wife needs consoling/help in her psychological

state. The hu*****and is more reasonable and and is in a more steady state to interact with the kids. Ideally it seems that a divorce is not needed. Maybe they should try separate for a while. They can still live under the same roof, and the wife can take some time "off" from taking care of the kids and focus on getting her psychological state better.

If that's impossible, they should get joint custody of the kids. Let the kids stay with the hu*****and on weekdays and let the wife take them out for activities on the weekend. The wife can also cook some yummy food for the kids on the weekend. Seriously, food is not the most important thing for them at this age. Their happiness is more important. (They can have similar arrangement if they live under the same roof.)
