I have to say... None of these posts are painting your wife in the best light. I can only speak to what I have read, so I write this as a reaction to that. Please take it with a grain either way. All choices are ultimately up to you alone.
That being said...
It sounds like while you yourself have made good strides to be a different and better person than you were in the past, your wife definitely hasn't. It also stands to reason that she might be a large part of why you sometimes seem to struggle with things of that nature still lately.
You are much too young to be going through such bullshit AND too old to be putting others through it as well, be it as the catalyst, an accomplice or an enabler. People in the service industry work HARD. And they take a lot of shit from people. Who your wife is when she's drunk is her true filterless character.
The fact that she treats people that way is disgusting. Especially her own husband. I hate to say it, but you need a new wife OR some serious couples therapy (she needs the majority of it) regardless of what you choose to do, I hope it ends up happier in the end bc I can sense the " I really don't know what to do" in these posts. But the good thing to remember is that bad times don't last forever. 😊
