Bf obviously doesn’t want to go to my uncles memorial

i have been dating my bf for 2 years. he used to want to be around my family in the beginning and has always been up to it. my parents are very nice to him including all of my family.

my uncle passed away a couple weeks ago, my dads brother. my bf never wanted to visit him in the hospital which i understood because he has only met him once. but there is a celebration of life in a couple weeks and my sister and her bf is flying out to go. i told my bf about it and he said “maybe. i have a lot of stuff to do” (which is bullshit because the weekends is our days to hangout and he no real obligations. he doesn’t really make an income anyways, he makes art.

i told him, it’s on a saturday and we have no plans. we can go for an hour but i would really appreciate it if you would come because you haven’t seen my family in 6 months.

he got very defensive and said “i don’t know the guy. i don’t feel like talking to anyone” etc etc. is this wrong of him to not want to go to my uncles celebration of life/memorial. i find it horrible since i see his family every weekend as i drive every weekend to see my bf. he never comes to see me and we live an hour apart.
