Sounds like he's playing with fire. He's agreed to seeing a counselor IF it happens again. By then, if you're committing to your word, he'd need a counselor to support him through the divorce. Too little too late. I wonder if he'd be open to seeing a counselor NOW to help prevent it from happening again. If this is ADHD related, it's a reason, not an excuse, and a counselor or psychiatrist can help him with his impulsivities since it's clearly damaging his marriage.
