None wed the second but who killed the first.

Wormwood. Wormwood.
This line has the remarkable quality of sounding like a saying, as in:

Like they always say, “None wed the second but who killed the first.” Or “A stitch in time saves nine!” And so on.
But of course it is an insane saying.
To suggest that every re-married woman is a murderer is nutsy pants. But the genius of this line is that the sound of it makes it sound like a thing. Like, that old chestnut spousal murder!
Also, it’s chock full of meaning for the wider vision of the play – Hamlet’s response to it would suggest that this might be a line he put in. But why? As far as he knows his father was murdered by his uncle. End of story. No murdering required of his mother. Or perhaps this is a little misdirection – look over here at THIS impossible proposition! But – really, we all know it’s this other thing.
Oh good old husband murdering!
Happens all the time.
Except it almost never happens.
Wife murdering, okay. That’s actually a thing. A third of all murdered women in the USA were murdered by their male partners. 
And when it does happen, that is, when women murder their husbands, it is almost always in self defense after a long period of domestic abuse. None wed the 2nd but who killed the first after a long excruciating period of violence and abuse that finally came to a head and she killed him to survive.
That old chestnut.

In second husband let me be accurst!

Careful what you wish for there, Queenie!
We all know where these sorts of curses lead. Straight to accursed 2nd husband, in this case.
Myself, I’ve learned to never say never.
“I’ll never more to NYC,” I said, before I moved to NYC and stayed for over a decade and a half.
That’s how this sort of language works. If I declare that I’ll be damned before I sink into that kind of poverty again, I’ll be looking at either damnation or poverty or both, before the 2nd act.

Such love must needs be treason in my breast.

On the news quiz show, they mentioned a study in which a large percentage of the women surveyed had back-up husbands in mind. That is, there was some man that they knew that they had visions of turning to should their current marriages not work out.
I guess it turns out that a large percentage of married women had this kind of treason in their breasts. It’s kind of a small treason though, isn’t it? And potentially evolutionarily sound.
Like, if evolution has us partner up for the benefit of children, should we lose said partner, it might be good to have another in mind to help us and our genetic line survive.
But, sure, treason in the breast. Okay. I mean, just because one thinks about a 2nd career as a fireman when one’s singing career doesn’t work out doesn’t mean you’re committing treason against Plan A. It just makes sense.

And thou shalt live in this fair world behind Honored, beloved;

On a good day it can feel like a fair world, though it’s rarely fair in the sense of just. Beautiful, it can be. Sublime.
Ridiculous. Invigorating. Surprising. Interesting. Shocking. Banal. Frustrating. And always complicated.
The days that are beautiful are ones to cherish. I don’t know many who honestly find each day beautiful. There are those that attempt to –
But sometimes that beauty is dimmed by the attempt.
I imagine the world is never so beautiful as when you are leaving it.

My operant powers their functions leave to do.

Let’s re-frame. Let’s try to approach life like the Player King.
We’ll think of life as full of operant powers.
We’ll recognize their functions.
Instead of worrying over making a life, of making a living, of doing something of note – we’ll worry about giving our operant powers their due.
What can we do?
What functions do we wish to perform?
Even the most mundane are miraculous when you think of them. We not only feed ourselves, we find and prepare food. We walk. We talk. We dance. We have sex. We relate to one another in abundant ways.
There are those who expand their functions beyond the quotidian – those who become athletes and circus performers – those who become opera singers and virtuoso musicians. Functions at their peak – those who have abundant operant powers.

Where little fears grow great, great love grows there.

This must be why my theatre life fills me with terror. It’s that horrible great love of the goddamn theatre. It is a great motherfucking love and the little fears get bigger everyday. Although not all of the fears are little. The “will I ever be able to make a living doing what I love?” one is actually not so small.
But there are little ones that grow big, too. Can’t think of what they are at the moment. But there are. I’m sure of it.

Where love is great, the littlest doubts are fear.

My first real committed boyfriend was a big fan of a book about relationships which featured a concept called the Upper Limits. It postulated that relationships often followed a roller coaster pattern of going way way up – then falling quickly down because the way way up led people to a place where they felt they couldn’t get any happier.
Couples who are so blissed out in this love state will often find some way to plummet again, for fear of the maximum, of going so high you just run right off the rails of the ride.
They’ll find things wrong, they’ll stumble into quarrels over little things, they’ll get insecure or fearful.
We ran into this problem a lot in that relationship – though, in retrospect, I’m not so sure that the upper limits were quite as high as we thought.
