Sotto,

when I got married I promised commitment until death do us part.
Now my wife has become mentally ill because of her troubled childhood and wants to divorce.
I will still be committed to her and to our children forever, and I encourage everyone to think the same way.
Just because one spouse has become mentally ill, it doesn't mean that the other one should do the same.
Your children will see you as a hero and as someone who never gives up.
