I don't go to Funerals unless it my family

I had a friend whom never came to any of the funeral where my mum died, my nana died and I was alone there mourning, griefing, and I spent the weeks isolated and now he lost a family member himself he telling me if I don't come he will not be my friend. I drank my tequila shot and look at him dead in the eyes as I spoke if that is the case then we weren't ever friends to begin with. Go with your wife, your mates, your family because no one tells me what to do, even if it respect someone loss does not outweigh my own loss and lack of respect. He was the first person I told when my Mum died and he did not appoach me at all or asked when the funeral. If it makes me the asshole then so be it
