Go to the funeral. You don't have to go to the get-together afterwards. The funeral part is completely different. Maybe explain that to him. He is grieving and try to be understanding, even if he is being an ass.

That was totally unnecessary. I'm sorry op :/

So much the better. You won't have to buy flowers to put on his grave. But seriously you don't need an invitation to go to the ceremony or to the burial. They take place in public places.

you don't have to be invited to funerals. You want to pay your respects and say goodbye, and you have every right to do so! Screw him and what he thinks!

If you still want to go, do so - she was your friend after all. In fact, bring something along to supplement their food and to show you do want to help and understand in their time of grief and sorrow.

Funeral invites?

You can always do what we do in the south bring a dish to share and visit to say good bye to your friend

I don't know... Perhaps the one who died didn't really care for OP and complained a lot about her to her husband... Some people have friendships that are one sided

Have you perhaps been to an event where you DID eat all the refreshments?

Do you usually eat everything but the drapes?
