Need Advice: 21 Year Old Live at Home with No Direction

So, first time posting - really looking for advice here. Serious responses only please. I have a 21 year old son who still lives at home. He has an "ok" job - works 40 hours a week and makes few bucks more than minimum wage but that's about it. He has tried going to school but does care to focus and usually gets C's and D's in his classes. Education has never really been that important to him as he hasn't connected the dots between a decent education and a job that pays above the poverty level.His mom and I do fairly well financially - and I fear we've spoiled him. He has never wanted for much of anything and seems content to live in our basement, work his job with no direction in life. He has a few friends but rarely goes out and seldom leaves home. He does have a girlfriend, which as become the catalyst for this post.I have been on him for the past year or so trying to get him headed in some direction. If he doesn't want to go the academic route I was hoping he might find a trade he wants to pursue. However, he doesn't seem to put forth any real effort to do so. Frankly, his life is just cushy enough that he doesn't have the motivation to do anything else. And I just don't understand it.Recently he got a new girlfriend. She seems nice; met my wife but I have never met her. Just this night he informed us she would be coming over at around 1am and staying for a few hours. It was this announcement that brought things to a head. (It's worth noting I have younger children in the house)My position was this was not acceptable. If she wants to visit she can do so at normal hour and if their collective work schedule makes it difficult to do so then that's too bad. I am not supportive of another "adult" in our house at that hour when he collectively doesn't have the rest of his life in order. My position is that he is living under my house and therefore my rules --- if he wants that sort of freedom then he needs to start making his own way in the world. I am interlinking these issues, for certain, but I believe this life needs to be a little less comfortable if a change is to occur.My wife's position is that she doesn't mind. She would rather have them here at the house then elsewhere. I find her position of concession to be exactly that which is contributing to a 21-year old listless child.So - here we are. I am the odd man out because my son just stormed out of the house and my wife stormed off to bed because apparently I'm the asshole. I feel like my wife is enabling him and I am alone in this.SO Reddit.. what do you think? I am out of line or being overly zealous? I would appreciate any guidance.... via /r/Parenting https://ift.tt/2n1HdpU
