My DH is generally quiet and reasonable but can be prone to argumentative and aggressive behavior, particularly when he's had a drink. We have two teenage girls, oldest is 15. Everything is good in our lives, we are very lucky. But recently DH slapped our eldest on the face when he was drunk and she was being what he'd regard as disrespectful. She slapped him back, my youngest told him to stop by which time I was in the room. In the past I have known my DH to be verbally nasty, not in what is said, but in tone and he has grabbed their wrists firmly in the past. I've always told him i wold leave him if he ever hit the kids and I've always told the kids they should never tolerate any abuse from anyone. DH is remorseful. Should I insist on him getting help? Had this happened to anyone else and did getting help work? Should I be worried?
