Then seriously, be direct to her, let her know your feelings and ask if she feels the same!! if you can’t do it this way, just write her an email!! thats it!
Still, in my opinion, love happens gradually, two never needs to ask and confirm the Love thing.. it gradually occours in your heart and you come to know after you have already crossed miles.. I don’t know why can’t you “get” what she thinks about you.. do one thing, Uski kisi friend se friendship karo… sab set hojayega!
