My fiance and my family members funeral

Sweetness • Mother of 2 soon to be 3, cannot wait until I get to see my little peanut!!
Tomorrow I have a wake to go to for my cousin who died of cancer at 22, my fiance tells me he thinks I should go to the funeral alone and leave the kids here with him. He shouldn't have to go because he never met him. Am I wrong because I want both my boys and him with me at the funeral? Or is he just being an insensitive prick?
