Last night I went with my husband and his Mum to a concert. Between 6.30 and 9pm he drank 5 glasses of wine . I had one and a cup of tea. We came in his car and I offered to drive home. Back at the car my husband got into the driving seat and argued he was safe to drive home. It took me and my MIL’s combined efforts to get him to move over and let me drive. Including me walking away to get the train at one point. He then sulked for the whole journey home. AIBU? Was he safe to drive?
