So me and a group of friends are planning to go to an anime convention together. I wanted to invite this one friend, (let's call her "Chris") but this would make the friend (let's call her "Jess") with whom we are all staying uncomfortable. Chris is a dramatic, easily offened person, and that plus her actions after hanging around my friend Jess, make Jess uncomfortable with sharing a room with Chris. Needless to say, they're are not on the best terms right now. I had already mentioned the anime convention to Chris, so I'd feel bad for not inviting her, but I also can't because of her it's Jess's decission to make. We already have several people going so I was considering telling her that we wouldn't have the space for her, but that feels a little dishonest. However, I don't even know if Chris would be able to/want to go to the con knowing Jess is there. If anyone has had this happen to them or has some advice for me, please help!
I don't want to sound whiny, but I'm feeling very conflicted at the moment.
