Help wtih a difficult situation?

My husband's childhood friend died 2 days ago at the young age of 40. He leaves behind a wife and a 6 year old son. His friend died by basically drinking himself to death. Drank so much, for so long that it caught up with him - his liver basically gave out and he died. Anyway, I am going to attend the funeral m with him, but now he tells me that the family (who are also drunks) are having a wake for him too! A wake is basically a "party" where they all get together and get drunk and reminisce about the deceased. The family is asking for everyone attending to bring lots of beer and whisky! I find it disgusting that the family is choosing to do this, given how he died! I told him I don't feel comfortable going to this "wake" and I'd rather stay home. I think he is mad at me, but I am sickened by this and do not want to go! Do you think I am being unreasonable? Thanks for any input!
