i know the situation you find yourself in, but there isnt really a clear answer. you cant just make someone fall in love with you. you can be there for that person and respect her decision. if you truly love this girl, then oud want her to be happy, even if youre not the person that makes her happy. one day youll find someone that loves you and you love as well, and im sure you wouldnt want anyone to interfere with that. just make sure you respect her decision .
