AIBU to drop a friend for driving over the limit with MY child in the car?

[RoseGarden123]

Attended a family function at the weekend. I went over early to help set up and family friends brought my DH and DS over later. Had a lovely time and during the event I saw that friends who were driving each had a very small glass of wine but nothing that overly concerned me and the event was 6 hours long and this was at the start. The driver even commented he was just having a small one as part of a toast as he was driving.
They left at end giving DH and DS a lift home whilst I stayed behind to help clean up. During chatting in the kitchen area it came to light this friend had come out back to the kitchen on 4 or 5 occassions and downed either a large glass of wine or a spirit, apparently telling the catering staff 'not to tell the wife'. From what i could work out he had at least 2 large glasses of wine, a glass of champague and 2 glasses of brandy, and all towards the end of the evening. I don't doubt this as so many people saw him but they all assumed his wife must be driving.
Obviously my 2 year old DS will never, ever travel with these people again and I raised it with my DH. But I am still fuming and want to challenge him over it, though I know it risks the friendship. However my view is he has completely broken my trust by taking this risk with my son and that is unforgivable. Am I overreacting?

Reflecting on this some more and some of the comments here, I don't want to isolate wife if there is a bigger problem here. I may try confronting but in a calm manner, saying how unacceptable I find the bahaviour, how it has deeply upset me and DH and how it has resulted in us losing our trust in him, I will also be clear that I would not hesitate in calling the police if I thought this happened again. What saddens me the most is DS means a lot to this couple, they are older than us, they don't have children and they dote on our son. They spoli him rotten at every opportunity and relish any chance to be with him. I would hope a realisation of how seriously we take this may be a wake up call. If I don't say anything and leave it, and god forbid something happens and someone is hurt, I will feel that I was almost complicit in the risks taken by not saying anything. I will and always have done given the wife my full support.

It is a no brainer for me! 'Risking' the friendship is their problem not yours, they have already doen that as well as risking your loved ones lives.

Best wishes to you and to your friend - and her husband. This is going to be a long hard road. I do hope he hears this wake-up call - but as I said before, AA/detox/rehab can only work when the addict really, really wants to be clean/sober.

I would not drop te friend, but woud ever let him drive my chidren again

That sounds like a kind response, Rose. I wouldn't expect it to change his behaviour, tbh, but you'll have been open and not isolated the wife. She may well be very very upset but that's not your doing.

And what Deepredbetty said.

If he's hiding alcohol in the shed from his 'disapproving' wife then she will need you OP. I admire you for wanting to stick by her. But if he drinks drive to your knowledge again, you can't let the friendship cloud your judgement. Call the police. You sound very caring and I don't want you to have a tragedy on your hands. ((hugs))

YADNU - I cut a friend off completely when she offered my husband a lift home and told him she hadn't been drinking when I knew she had. I was just so livid that she would a) offer a lift when there was no need (other lifts available to us and her) b) lie about how much she had drunk so that he couldn't make an informed decision. I would have shopped her to the police but she was driving a hire car at the time and I couldn't remember the make or reg no, but we never saw her again and she's bloody lucky she didn't wake up the next day with her teeth in her pocket.

Thank you, I am going to speak to them this evening.

If I was sure his wife wasn't driving, then I'd have his head on a plate, never mind trying to maintain the friendship. You can't justify this.

Thanks - I'm sure his wife wasn't driving, it was the first question I asked DH when I got home. It is not about maintaining the friendship that I am bothered about, I am still fuming. As said above, as far as I am concerned he put my son and my DH at risk and that is unforgivable, whatever the circumstances. But i would like to offer him the opportunity to admit he has a problem and would suport his wife if this comes to light.
I still want his head on a plate but not sure that is the best or the most constructive way to handle it, when I really hope that this is a way of maybe making him think twice and not repeat the same action in the future.

Yes, of course. You're much nicer than me
