Husband hates son's girlfriend

Our oldest has been crushing on this girl all school year. He told me about her. That she's on the color guard which u thought was a military thing but apparently it's flag spinning. He's a sophomore going into his junior year and FINALLY asked her out and she said yes. My husband was excited because our son has never had a girlfriend. He's always been more into video games and building robots and computers than girls. We got to meet her at the end of year bash and I thought she was a sweet girl but my husband doesn't like her because she's bigger. He told our son in the car "She seems a little fat doesn't she?" And he got really upset that she said that and so did I. I told him that's awful and he got mad that I called him out in front of our son. I asked why does he care and he said he didn't Invision him dating a fat girl and he's disappointed. He said our son can date her but don't expect him to be nice to her. I told him he's not bullying this girl and he said then keep her away from his house because it's his home. I can't believe him! He was so excited and is upset that she's a little overweight?

@Alana.... This girl isn't trying to come between our family. She's just existing. I called him out because I don't want my son to think like that. My husband is coming between them by calling his girlfriend fat and saying he's going to be rude to her for no reason besides her being overweight. I am not afraid to call out my husband when he's wrong. If their relationship gets ruined that's on my husband. Not this girl who did nothing wrong.
