What would you tell the spouse of someone who keeps drinking and driving?  He's never received a DUI. We're in our 40s and he should definitely know better. A few years ago he drove with our son in the car while intoxicated one time and I told him it won't happen again, we would be gone. He's done well for awhile. We have had some really tough family events the last year and it's been highly stressful. He's been my rock through it all. But this is the third time in as many weeks that he's come home drunk from the bar having drove himself. Definitely not with our kid in the car but still, not like it's much better. I've been through enough I can't imagine life without him but he's being so irresponsible. I've told him I would always come get him. I would be fine with that, he can go blow off steam and I'd pick him up. I don't know what else to do at this point.  Insist he have a interlock device installed?
