Translation of cutie in Spanish

Let's not forget how we started. We were writing each other very long messages and today we are both much more fluent in both languages. No book could have brought us that far. Cheers.
Usually we write these messages twice a week. We also have a fanpage in Spanish where we need to write short messages. It is actually pretty boring but people respond to it. Don't ask me why they are doing it.
Thank you for your feedback, I have little knowledge of the German language, and at the moment I have to use the dictionary a lot, and I read many articles from online newspapers and magazines.
