Confusion I have a feeling with a boy. Sadly, the city which I live in now is far away from his. We haven’t had face to face talk since I left 2 month ago. Only by texting messages and making a few phone calls ,we get contact with each other . I know, in this way, I can never make deeper exchange with him. Once I asked if we can increase the number of calls. But he said that texting is enough. What he replied is somewhat hurtful for me. Now I am not sure if he loves me as he declared.

Happy Mid-autumn Day , everyone!
