No..they just want happy parents..so it is the parents responsibility.
Kids living under the same roof as two unhappy parents as opposed to kids having parents under different roofs but are happy ,would be in a much better position.IMHO.
What I meant was that kids want happy parents under one roof. All attempts should be done to meet this rather than giving up easily. I agree that seperated parents who are both happy is better for the kids than 2 parents under the same roof who are miserable.
