Translation of Lebendigkeit

I try to learn English as much as possible so that I can travel next year to the United States. I would agree to your proposal but I also need to find good teachers. My goal is quality and speed.
Thank you for your inquiry. Your Italian is very good. How long have you learned it? Last year I studied Spanish, which is very similar to my native Italian, but it also confuses you sometimes.
So you want to know what I'm doing? I am 22 years old and I am studying medicine at the university in Atlanta. I want to learn German because I have a German girlfriend. We want to get married.
