Reply "How much do you want me to contribute to our family finances? It was not my choice to rent a second apartment at this time."
Actually the second sentence is too much. But really, no HE can't do it all and no, YOU can't do it all. How can you homeschool and work full-time billable hours? THAT is not realistic for mental health IMHO. Something is going to have to give on one or both sides here, it seems. He can't work those hours to pay for two households and do that much childcare to AVOID paying child support. So he's going to have to choose. Or you're going to have to. Somebody's going to have to.
