She's not reading anything with you, she's not going to counseling, and you're the only one still trying.
So you typed "book save your marriage alone" because most marriage books assume there are two people at the table.
There's a short shelf written for one, and here are four from it.
Why a man reaches for a book
A book feels safe at night.
Nobody sees you read it, nobody has to agree to anything, and you can start in ten minutes.
So I don't think it's weak to want one.
When the whole house feels like it's out of your hands, a book is one thing you can do right now.
And I'd rather you reach for a book than for another argument at the kitchen counter.
I'll say this too, because it matters.
A lot of men pick up a book hoping it will tell them what to say to her.
That's wanting something FROM her again, only this time it's dressed up as homework.
The books worth your time turn you back toward your own side of the house.
First, about the word "save"
I'm going to be real, no book saves a marriage.
One reviewer of the first book below wrote, "you can succeed even if your spouse won't agree to work on the marriage".
That's his experience, and I can't promise you the same.
What these books do is give one person something to work on.
The Divorce Remedy, by Michele Weiner-Davis
A 7 step program for the spouse who wants to stay when the other wants out.
It was written to be done alone.
This is the one husbands on the forums bring up most when a wife has said divorce or moved out.
It's written for husbands and wives both, so parts of it won't be about you.
How to Save Your Marriage Alone, by Ed Wheat
A short faith-based book for when only one spouse is trying.
Reviewers are split, some found it steadying in a crisis and some felt parts of it were a little unfair to the spouse who got hurt.
Good if your faith is a big part of how you make decisions and you want something you can finish in a night.
Winning Your Wife Back Before It's Too Late, by Gary Smalley
Written for the man whose wife has walked out and who wants her back.
It's also faith-based.
It's one of the few on any list written to the husband only.
The Heroic Husband, by Noah Allen
This one's mine, so weigh that however you want.
It's a leadership-based guide for the husband whose wife feels distant, and it walks you through the 3 step Emotional Layering Method (ELM).
You read it by yourself and she doesn't need to be on board.
How to read one so it changes what you do at home
Okay, so whichever of the four you pick, don't read it like a novel.
Read a chapter, then stop and ask what that looks like in your house on a regular Tuesday.
Ask what it says about you, because the page can't see her and it has no idea what she's feeling tonight.
Then pick one small thing from the chapter and do it the next day, quietly, without telling her where it came from.
If you do it while watching her face for a reaction, you're pushing again, and she can feel that from across the room.
You see, a woman who's pulled away needs to feel safe with you before she feels anything else.
Safe comes from you being steady over weeks, and no single chapter gives you that.
Why a pile of books doesn't help
I've had men tell me, "I've probably read, like, 15 books in the past year and a half".
Another told my team, "I'm understanding it. I'm just not executing it correctly".
That's the whole problem in two lines.
Understanding is the easy part, and it feels like progress because your head is full.
But then it's dinner, her face is cold, and what you underlined is gone and the old reflex is back.
A book can't sit at the table with you at that moment.
So a fifth book on the same shelf only gives you more to understand, and the next night looks the same.
Read one, all the way through, and then live it for a while before you buy another.
What I can't tell you
I can't tell you she'll come around.
What she's thinking is hers, and none of these four authors can tell you either.
If she's talked about moving out, or you're facing questions about money or custody, talk to a lawyer in your state.
A book is not the place to get that answer.
What reading alone can change
You can change what it's like to be around you.
Whether that changes what she wants is up to her, and no author knows the answer to that.
One thing to do tonight
So pick one of these four.
Just one, and write down the date you'll finish it by.
