TBF it is still binge drinking even if it is limited to drinking yourself into a total state 4-6 times a year.
It’s about episodically consuming a large amount of alcohol in a short space of time.
It’s not about not texting or phoning your anxious wife though.
Clearly the OP is right that pissing the bed level of drunk is not ok, but she has even admitted that (on another thread) she feels this out of control drinking on these occasions is influenced by her demands to appease her anxiety.
Which BTW used to be demanding he tell her every detail of where he was going, for how long and who with and now has been reduced to demanding he tell her how long and text/call if going to be later.
She’s detailed in other threads that some of the occasions where he has been very drunk have been in response to things like her threatening to divorce him if he doesn’t come home.
His binge drinking is not good for him, that much is true, however I do think his excessive use of alcohol on those occasions is most likely his maladaptive coping mechanism for dealing with the OP’s demands.
If the OP was less extreme about him going out at all then it would be easier for them to discuss the times when he has come home in a total state IMO.
