I can't take it. Seriously.

The fact that no one else but you all will take him in, says to me that you are not the only one who feels this way about him.

Your DH isn't home to see him interact with the boys & he needs to know whats going on in the house. Don't view it as dumping on him or burdening him. You are just informing him what is going on during the day, just like you tell him what the rest of the family has been up to and letting him decide what he thinks about it.
