Japanese language

The post on the Japanese Language Proficiency Test published few days ago reminded me of what I had planned before the beginning of the year as part of my New Year’s Resolution, learn Japanese. Well… let me tell you that, as usual, after a good start I kind of stopped studying the language. The Japanese girl I’ve been dating is trying to push me to study and is happy to help me but I think that it wouldn’t work, I want a girlfriend not a teacher. I need to find a way of keeping myself motivated. Any ideas?
