A lot of the replys to this thread made me laugh.

Does she even speak english? It sounds like you have a communication problem with her.

You "made" her your girlfriend? What does that mean? And "I'm pretty sure she likes me"? You should find this out for sure since you already made her your girlfriend.

Finally, I'm not completely sure about this but, I think it's also customary in for the male in those relationships to get some on the side. I know someone living in Thailand who's in a similar relationship. But he said it would be acceptable for him to get some from another girl. If it's true there, it could be true for Japanese girls. I don't think there are many old traditions that involve guys not getting any. Usually it's just the girls. Look into that.
