--I am not sure if this is enough of a sign to send the message of detachment... but if you want to stop paying to send a signal --then just say, I have decided to stop paying these expenses for you.... That is it.... do not say anything to do with you... "I feel like I am being taken advantage of" IMHO

Practice what you say in response to --Why?? Just say again, I decided to stop paying,,,, etc.
