Please help?

Alright. So I’m having this party. Just one I thought I’d have to hang out with friends and have some fun. My mom helped me put it together and pay for it.

There are a lot of people going. But three of the girls I invited happen to be my best friends. Melissa, Kelsey, and Brianna. Well, we all used to be really close. We had our ups and downs, but it never made us further apart. My party is a week from tomorrow, and Kelsey and Brianna just got in a big fight with Lissa. They don’t like her anymore. The invitations were supposed to be handed out today at school. But I held back. Because Kelsey and Bri really don’t want her going… but I don’t want to just not invite Lissa. That wouldn’t be right. I would just go ahead and give her the invitation, tell her that if she feels comfortable going then she can. But Kelsey and Bri aren’t very nice to people when they’re mad at them.. and Lissa’s a pretty sensitive person. I know Kelsey and Bri aren’t being good friends towards me at all, but it’s who they are.And honestly, If I got in the fight they got in I wouldn’t want her going to the same party I’m going to either. But I have nothing to do with the fight. So like, I don’t know. I’m confused.
