I think at a certain point in life, if you don’t have the self-control to not explode at another adult simply because you don’t get your way, one should seek anger management help. Adults throwing tantrums should in no way be normalized or played down. It’s damaging, hence the relationship breakdown. I’d view it the same way whether the person on the receiving end were 3 yrs old, 43, son, spouse, or friend. The damage may manifest differently depending on the relation, but damage is inevitable in one way or another.
The only answer is to work on one’s self so that out of control anger doesn’t isolate any more loved ones. I am blessed to not be exposed to anyone with explosive outbursts of anger, but I cannot imagine I’d desire closeness with anyone after being on the receiving end unless that person was willing to cease the behaviour and work on themselves.
