Recently my friend and my best friend had a big fight and now they just hate each other. After the fight, both of them were trying to get me on their side and now are getting mad at me for staying friends with the other person. They are trying to convince me not to be friends with the other person. I feel like the friendships with both of my friends are breaking. I feel pressured and I don't know what to do... I don't like to choose sides and they are both great friends.
