Let me add to what Jilly said. Your kids are being affected NOW by the sick relationship you and thier mother have.

1. Your son was suicidal and needs mental health help
2. Your daughter has an eating problem and eats to cover up her confustion and hurt.

So, you still have time to divorce thier mother and become a healthy strong role model for them. But not much time. Those kids are troubled and affected every day by that selfish disrespectful mother and by you, the supreme enabler.
