NC for this as potentially outing info. Looking for advice as to what other parents of older teenagers would do in this situation as I'm a single parent and don't want to discuss with family at this point.
There's a bit of backstory so bear with..
I bought DS a car for his 17th in January that he absolutely adores and has been doing up as a little lockdown project as college work has been sporadic at best.
He was actually given a sum of money at Christmas by grandparents that technically should have been to buy a car but he blew it all on other things within a few weeks, leaving himself without enough cash to buy one. That really annoyed me if I'm honest and if this was normal times and he was still working I wouldn't have bought him the car, I'd have left him to save up himself from his wages.
So I only really bought him the car because
a) he's been furloughed from his part time job since October and can't save for his own and
b) because he'd quit smoking after a 3 day HDU admission in October with a life- threating asthma attack that medics really struggled to get under control. It's taken him months to recover and is on a big increase in medication.
So the car was a "Happy Birthday" and a "well done for quitting smoking", and a motivational project as morale is pretty low after the last 12 months.
The car is in my name and I'm paying the tax and insurance until he passes his test.
The last few days he's come home from "exercising with a friend" absolutely reeking of tobacco..
I confronted him and he said he'd been standing too close to his friend.
The same happened last night and he eventually admitted to smoking "half a cigarette".. but I'm pretty sure it's been happening for a few days now.
I saw red internally if I'm honest, but didn't react I just calmly asked him to give me the car keys and I'd speak to him when I'm ready to. That was last night, he's still asleep so haven't seen him today to speak to but I'm still not calm enough to have a productive conversation.
My question is where to go from here.
I feel that I need to really hit home with a strong message and quite honestly at this point feel so let down that my urge to just sell the car and let him save for his own once hospitality reopens is very strong.
I'm aware that this is a big reaction, but I'm at my wit's end with the smoking (have tried everthing previously) and perhaps naively thought the car would be enough to keep him on track. He knows I wouldn't have bought it had he been smoking, I'd made that clear.
So it's all a bit of a slap in the face as aside from everything I'm not exactly rich, I dipped into my very meagre safety net savings for it because I wanted to help him out.
I don't feel as though I can just roll over and say- "oh you just carry on smoking and risking another hospitalisation on oxygen and a drip and hey, here's your car keys!! ...
So, with all the above considered...WWYD??
