Well, I asked my mom about the thing with cosigning. I reminded her that she shouldn't wait for my grad school outcome to decide their living arrangement. They need someone else who can /actually/ provide
Thankfully, my mom has thought of asking her brother in Louisiana in case my situation falls through, but yeah, ultimately, all I can do on my end is wait for grad school to tell me if I'm accepted. Asking and talking to me about it every night isn't going to change things.
