Tips please on how to approach him about this? I want to do it in a sensitive and loving way. I think a diagnosis would help. Or at least if he could read up on it.
We are having problems. Happy to try to make it work but I need him to understand this goes both ways.
Infuriatingly, he seems very against counselling and therapy. 
Is there a way I can convince him otherwise? This is to benefit him, and of course, our relationship.
I’m not a psychiatrist but it’s so glaringly obvious - to friends, sales assistants in shops etc it cannot be denied anymore and I can only do this if he’s prepared to get support for both of us.
