I'm glad it worked out. But in general, if you're friends with two or more people who don't like each other, and one or both of them tell you that you can't be friends with the other, then tell him or her that being the other's friend does not make you disloyal or a bad friend. It's her choice if she doesn't want to continue being friends, and I know it's hard to lose a friend, but real friends don't try to manipulate you. You can be friends with people who don't like each other, as long as you don't gossip between them and don't reveal personal information among them.
