If your SO wanted you to go to a party but you didn’t want to, what would you do?

My boyfriend always wants me to go his family’s parties but sometimes I’m just not in the mood. I understand it’s his family and all, but I can’t help it if I’m not in the mood. Plus he likes to look nice so he makes me straighten my hair and put on mascara to look nice too. (I hate doing my hair/makeup and he knows that)

We were raised completely different, my family doesn’t really care how we look at parties but his family is the opposite, they like to dress up. So getting over that is pretty difficult in our relationship.
