Ending Friendships

I’m currently not talking with a friend as we had a dilemma happen. It almost feels like our friendship will eventually break and I don’t know how I’ll deal with it. At the same time, I think it would be the best for the both of us to go our separate ways. For any of you reading this, did you ever go through an experience of having to break off a friendship because of something? And if that happened, how’d you deal with it? Do you think it was a good decision?
