Translation of say goodbye in German

I would like to have you as my good friend and maybe we can go to places in the near future, and maybe we will travel together to China as well one day (if you wish to go there). Tell me more about yourself as I will love to know about you.
I can understand a little Spanish with the base of Italian and heaps of words sound familiar. I will try to have conversations as much as i can. Just learning the vocabulary and the grammar isn't enough!
I did not feel well that night and we decided to stay in our room. My wife brought me fresh take away salad. We were exhausted from our day and watching a movie was the right thing to do.
