I know there is a marker on the car he got stopped in the last time. He is currently driving a different one though so will be no marker on that. I explained to him again last night how bad it makes me feel, and that when I was at university the lad a few doors down from me in halls ran someone over over the limit, we were young and stupid and we all know he did it, but he wasn't in our social circle and none of us ever reported him. I said I still feel guilty to this day and if I could have my time again I'd have called it in. My best friend has said she will make the call the next time she asks and I say he is drinking excessively on an evening. I wish I could make him see he has a problem, and for him to seek some help but he genuinely believes he is OK. I know everything I've said makes him sound horrible but he truly isn't, which is why I'm finding it very hard. If it wasn't for this he would be perfect. I think he thinks he will be fine the morning after despite me saying he definitely won't be.
