I am sorry your son is treating you this way. My son, who is 22, was doing very similar things. Do what I did. The next time you talk to him, tell him if he is not polite, you will hang up and not talk to him for no less than (insert your number of hours). I said 48 but a couple of times I made it even longer because I just couldn't handle the verbal abuse. I would unplug my house phone, and block him on my cell phone through the carrier. We don't use the house phone much but this was an inconvenience but worth the silence. It was hard at first but it was also some of my most peaceful moments. I can't say all the demands have stopped but they have definitely reduced and the cussing is much less to almost none. I refuse to send any money. I do still occasionally help but only if he is polite and only on my terms, meaning only if I feel I can afford it without hurting the household. It is hard but if we don't give in, they will figure it out.
