I am so angry!!!

Me and my father, sister, and brother were in Disneyland and we were talking about significant others. I was talking about my boyfriend and said s/o instead of it and my dad gave me this weird look and then my family started in on my boyfriend. My brother said “but he’s so ugly!” And my dad said “I really hope you don’t stay with him” my sister later said “I really like him.” But this pissed me off because he makes me so happy and for them to judge him so harshly when they don’t even really know him just UGH!! My brother has only met him once as he has been away at college and my dad has met him a few times. Why the hell would they do that??
