How do I get him out my home if he was diagnosed with schizophrenia, is bipolar and he refused to take meds?

You will have to file for divorce and bring a motion to have him removed from the marital home. It is not automatic or easy, but on the facts portrayed may be possible. You also have the choice of moving yourself and the children but, if a case has been filed, will need the permission of the court to remove the children.
