I could easily send H a message, detailing how he's cut his support by $1,300/month and out-and-out ASKING him if he expects me to stop paying the mortgage since his name is on the mortgage. I don't know if that's the best way to approach/word it, strategically. But I KNOW that's what he intends for me to do.
Yeah, that's what I'd do. I'd keep it chatty (so not to tip him off), and say something like "I know you keep telling me to stop paying the mortgage, but I didn't want to do that without asking you first, since it's in your name. But really, since the groceries, haircuts, doctor co-pays etc add up to easily $______/mo, I guess I don't even have a choice. Or am I figuring this wrong? Hey, I was told there'd be no Math!!! lol"
