So I have a very large close family my mom has five sisters and I have lots of cousins that are more like siblings. My husbands side is large also and parents are divorced and remarried so he has lots of people to. My sister is throwing me a shower and paying for it, is it wrong if she just has it for our side? If she includes his side we will have to rent a hall and I know they won't kick in. His mother gets quite offended by how close my family is and how much time we spend with them. But she rarely calls or invites us over. I don't want to step on toes and don't want to make my sister include them all when his mom has been very rude to her in the past. She is very political and opinionated. Help!
