Prepare thefor christmas

I decorated the christmas tree with my girlfriend.

You could also say "my Christmas tree" or "our Christmas tree"

Honestly i I am not really a traditional guy, before she i did not keep thesetI did not decorate before her, but i tried to change my mind and it was good feeling with her.

I am not really sure what are you trying to say here. Possibly something like "Honestly, I am not really a traditional guy. I did not decorate before meeting her. I have changed my mind because it makes her happy."

I think this times in of the year is a special time because everyone trieds to relax, beacause everbodyyone is trired from year working all year.
