Short answer: yes. Longer answer: it works for a specific reason, it has real limits, and you should know both before you start.
The reason it works is that a relationship is a system rather than two separate people. Every recurring conflict is a sequence that requires both of you to complete it. You say the thing, they go quiet, you follow, they leave the room. Remove any one of those moves and the sequence cannot finish in its usual way.
So the work is narrow and quite demanding: your half. What you do at the moment it tips. The sentence you say two seconds too late. The pre-emptive defence you have stopped noticing you make. The story you tell yourself about their motive within about a second of their behaviour — which is what you then respond to, rather than to them.
Clients are often surprised by how much moves. Not because they have learned to manage their partner, but because a person who is no longer being pushed responds differently, and because a great deal of what felt unbearable turns out to have been the loop rather than the marriage.
There is also a second thing that happens with individuals, particularly those on their second or third version of the same ending with different people. The names change and the shape does not. That is almost never bad luck. It is a pattern learned somewhere, running underneath, and it is very hard to see while you are inside a live relationship defending your position.
Now the limits, honestly. One person cannot repair a betrayal alone — that needs both. One person cannot make an unwilling partner change, and if you arrive wanting techniques for that, I will tell you in the first call that this is not what coaching does. And if there is active physical, sexual or coercive abuse, coaching is the wrong instrument entirely; that needs a specialist service, and in India you can reach the National Commission for Women helpline on 7827 170 170.
What frequently does happen is that the reluctant partner joins later. Not because they were persuaded, but because something in the house changed and they could feel it. That is a much better reason to walk into a room than an ultimatum.
And if you are working out whether to stay, this is the right setting for it. You get to think clearly, away from the worst version of the argument, with someone whose job is not to talk you into either answer.
