OOHC says:"I keep copies of them and sometimes when I am having a bad time or questioning myself about whether I did the right thing I look at them so I remember just what it was like and why I had to leave"

I do the same thing. My jewelry box has folded letters of confessions, descriptions, etc written by him. I've had them for 3 years. I plan to keep them, for myself, and for our son who may have questions when he is older.

If you have an attorney ask her/him about how his behavior may work in child custody. Bringing drugs and strangers into the home when the children are there should be important, particularly when the strangers are "professionals" and may have criminal histories.

If he has a parent or sibling whom you would trust to be present and not let him take the children out without him or her, ask the attorney about the possibility of him having contact with the children at that home.

Rely upon your attorney as to whether bringing something up will work well before the court. That's what we pay them for.
