If your loving your friend and she doesnt show her real intentions.
Sorry if this sounds harsh, but if she doesn't show her intentions let her go. If it doesn't feel good don't do it.
Love is the hardest lesson in life
There is another girl Who will live you the way you are. Don't let her play games with your heart and don't force her or love that wouldn't help you. Let her go or you have to talk with her about that. Maybe she didn't notice that you love her or she don't know how to tell you that she don't want to have a relationship with you. Love hurts and love repairs that's normal
