I am a young bride, so lots of my friends are still in high school. I want to invite one of my closer in high school friends and her mom, who I also know very well. My problem is, is that I don't really want to invite her whole family, because I don't really know her dad at all, and I am not having kids or younger teens at my wedding except for family, so I don't want to invite her brother. Her brother is a younger teen, but in my few encounters with him he is very unruly and I don't really want that. I feel bad only inviting 3 of them, I also considered only inviting my friend, but I don't want to give her a +1 because I really don't like her boyfriend, and my mom is also very against the idea of her boyfriend coming as well. Is it okay to just invite her and her mom? What should I do?
