Once again I am so very sorry. No family should ever have to go through this. You are among others who understand all too well.
These behaviors at 14 (or at any age, really) are very, very alarming indeed. I am so glad that his dad has taken the step of signing his rights to CPS. This will allow the child to be appropriately placed. And while I have never been through this and don't know for sure, I would guess that once he is a ward of the state you are no longer obligated to take him in.
You sound very strong. I hope your partner is on the same page. It can be very difficult when partners do not agree on how to handle a child. I am a step-parent myself so I know what it's like to be in this position as a non-biological parent.
