Did he ask if you minded that he went still? If not, and I needed support that evening, I would have asked my partner to stay with me (he often doesn’t think!) Perhaps he may have thought you’d like some space? Just trying to think of it from his perspective even though I totally understand how you must be feeling. Sending lots of love and I hope your Dad is as ok as he can be xx
My mum died of cancer in January, it was just as hard on my partner as we both loved her, we both are grieving in different ways but you should definitely express how you want to be supported for sure! It might have been his way of needing to cool off after the news, or he might of thought you would need some space to process it x
As someone who’s mom had cancer you can’t expect people to know your needs. I would just express what support looks like for you. My husband prefers space and normalcy when going through things and I am more of wanting support and cuddles
