He's been spiraling down since he turned 18. We had a mtng the other day, and he improved slightly. He came home for dinner tonight. Today he drove the car home with a smashed passenger side mirror and a scrape on the front right hand side above the right wheel. He said he had parked it on a small side street near school, and when he came out this afternoon, the damage was done. He's supposed to park in the lot, but we never had the $40 pkng pass moved from my windshield to the new car (Corolla). We both forgot. Well, at least I did. He goes to school every day so you'd think he'd remember at some point. At any rate, he told me over the phone that he had something to tell me but wanted to do it in person. He told me when he got home at 6:10. I told husband about an hr ago, and the 3 of us went to look at the damage with-a flashlight. The window was open about an inch. The car stunk like cigarettes. He insisted that no one was smoking in the car. Long story short, when they got back in the house, they started to argue. husband insisted that someone was smoking in the car (he's got asthma, I get migraines and it's a leased vehicle through husband's biz) and difficult child ramped up and they went at it. husband shouted, "I'm sick of you! Go upstairs!" And difficult child yelled, "Fine, I'll leave. I've been wanting to leave and have a life anyway." He added that he could stay with-a friend (the smoker, no less) who lives alone. Although the other day he said the friend lived with-his dad. Everything changes ea time he says it. I am very upset. I'll be surprised if he comes home tonight. husband thinks he will. It's 35 degrees and he's wearing a hoodie, and no socks. But he's got his phone.
