Enough is enough!

I was really loving this drama up until the end of ep 9, but 10 and 11 are completely ruining it for me! Does this chick not see anything wrong with spending all her time and special moments with her MALE “friend” (who clearly shows signs that he may be interested in more that she also clearly seems to pick up on but chooses ignore) instead of her boyfriend?! Her birthday! She spends it with him instead and doesn’t even call her boyfriend? I really what to know the rest of this story but I’m starting to think I’m going to end up dropping the series by the end of this episode.
