Forced Forgiveness

Me and my two best friends got in a fight with our other two friends because we heard that they were talking trash about us. After a long time of denying it, they finally came forward, but then were mad at us for being mad at them. Later on, me and my two best friends got called to the school counselor by them to work things out. By the end, our "friends" that were talking trash about us, asked for forgiveness and to be friends again. We felt obligated and pressured into forgiving them. Us three are still really mad at them but hide it. But I don't want to pretend to be friends with the two girls anymore. What do I do?
