Have n/c but am desperate.
Partner of 9 years always was quiet but I am at the end of my tether after 5 married years of silences.
He is not sulking, he just does not talk.
Things are at crisis point as our teenage dd is in tears at the non communication - I am the one who talks and interacts with the dcs and dd is very open with me. She says that she is receiving help at school with the atmosphere at home. 
Dh refuses to discuss this with the doctor or go for councilling.
I knew he was quiet when I our relationship started but it has become worse over the years.
I have suggested he reads dcs stories etc but have to constantly prompt him to speak. It is exhausting and demoralising.
Please can anyone advise me on how to cope with this?
