Absolutely get where you are coming from. 21 yo back from Uni, appears to have no intention of getting a job for about 6 months, and that is a maybe job not a certainty. Goes to the gym, plays on his computer and sunbathes.
When we get in from work he asks what's for tea? Will empty dishwasher, bin etc if asked. But in his own sweet time. It's like living in a student house, with 4am sausage cooking and leaving the pans out.
And breathe...
Fortunately I like him, he's a nice lad, but really doesn't do a thing unless asked.
DH is enabling it.
So I have backed right off. Dirty dishes I leave for him or his dad to sort out, him and his dad go shopping, or DH goes on his own. His dad now does most of the cooking. I find this much less stressful. DH thinks I should be supporting him in his, DH's efforts to son to do things, but, you know what, you bought him up like this...
I don't want him to stop living with us, but I was starting to feel like a skivvy and so have stopped doing stuff.
