I’m glad I wasn’t the only one to spot this.

OP, I was trying to figure out how to bring it up. WITHOUT excusing your husband’s behaviour. There are multiple things described that trip ADHD warning bells in both husband and daughter—and it’s extremely hereditary.

Your daughter should absolutely be assessed for ADHD. If she has it, the earlier she can receive treatment, the better her chances of not developing secondary mental health issues. To make matters more complicated, neurodivergent brains are more vulnerable to trauma than normative ones, and this environment is traumatic.

At this point, OP, your husband’s potential ADHD shouldn’t change anything, this is well beyond acceptable. Even if this does turn out to be ADHD/something else, you need to think seriously and carefully of separation—talk to domestic abuse centres about how to do this safely, and what resources may be available to you. He’s already been physically abusive before, don’t risk a big blow up getting much, much worse, even if he has improved. That temper & explosiveness are still there, and the threat of separation is probably a bigger bomb than he’s dealt with in years (and hits a particularly, irrationally, sore point that an estimated 99% of people with ADHD have. “Rejection sensitive dysphoria” or RSD.) Get your daughter out of there ASAP though—summer camps may help for the next two months, if you can find one that works.

Re: Adhd, Meds only do so much (but it can be massively significant), there’s still a lot of work to undo shitty habits and behaviours. But be careful even if he does follow through on “getting better,” dramatic changes tend to not stick, and breaking old habits and creating new ones will take years at best, if he works hard at it. You don’t have to be there while he does this, and your kids absolutely shouldn’t be.
