Tried to convince him to go back to the hospital multiple times, and so have his sisters.

I think he knows what will happy, and just wants to be loved right now, hence is staying with me here. Up to him.

What am I supposed to do? Demand he gets out of my house, and visits his mother in the hospital? Considering how erratic he's been acting, I have to treat him with kid gloves at the moment. Whatever he wants is what happens.
