That's a tough question. It really depends on the situation, honestly. If my best friend betrayed me, it would definitely hurt and it might change our relationship. But I believe in the power of communication and forgiveness. I would try to understand why they did what they did and see if we could work through it. Everyone makes mistakes and I believe in giving second chances. In this case, I usually try to remember their kindness to me in the past, despite their mistakes. So, I'll give it a second chance.
