Hi @Felicia29
there's no right or wrong way with any of this! Sorry to read about your partner however that is the coping mechanism he has adopted and unfortunately for you it would be nice if he let his guard down for a cuddle however I am sure in time you both will be in a better place emotionally to cope with what he has been through and what you are going through at present.
Me, I am a little different to most on here, never shed a tear and not likely too. I guess life's experiences prior set me up to how I reacted. What I do know is that acceptance helped me to cope with treatment and the ongoing anxiety that comes about with each upcoming review as well as the niggles of medication.
Please don't be hard on yourself, just roll with it, enjoy the practical support of cleaning and cooking and others have suggested the BCNA helpline is available if needed as well as the forum.
Take care and best wishes as you settle into routine with it all
