Boyfriends mum has died, how do I support?

[Newuserbekind]

Hi,

I've been with my partner 6 years, on Wednesday his mum passed. I don't know what to say, I don't know what to do, it doesn't feel like it. She's battled several months with cancer.

I'm so sad for how wonderful she was to me, my partner and his family.

What do I say?
What can I do?

Give them support, you don't have to say much. Or do much, stay there for him and the family and grief with me.

Just be there for them.
