I don't know if I can be happy for you.
It's been exactly one month since I broke up with you. I don't regret my decision, and I'm glad that we're on friendly terms, but you started looking for a new girlfriend less that a week after we split, and we were together for over two years. You haven't had much luck, but with every new Facebook friend, I wonder, is she going to be the one to replace me? I want you to heal from this and go on to live a great life, but if you find a new girlfriend tomorrow, I don't know if I'm ready to be happy for you. And I wonder, will things change between us? Will you decide to ignore me? Will we still be able to spend time together, like we did last weekend?
Ultimately, I wish the best for both of us, but the fact that you were able to stop loving me so quickly still hurts. I'm sorry.
