A marriage does not need to be finished before counseling is useful. It needs to be heavy. The usual signs are familiar in Jalgaon and in Pune: every talk becomes blame, the house is polite and cold, or one person has already started to leave without packing a bag.
What the sitting is, and what it is not
Marriage counseling here is not a court, and it is not a performance of who suffered more. It is a private room in which both people are asked to stay with the real subject. Sometimes that subject is respect. Sometimes it is money, a parent, a child, or an addiction nobody has named.
You may begin with an hourly consultation if you are not sure you can sit in the same room. A full session is better when the trouble has months behind it. Come together when you can. If only one of you is ready, say that in the first message. One person can start. The aim is still the marriage, not a secret.
