If a person loves u, he or she will be honest and loyal. she is not in love with you. Because love is above sexual needs and desires. She is taking u for granted. she knows u will be there for her. U are just convincing yourself that she loves you and you will be happy if you are with her. Being with someone who doesn’t care and love you will only make u feel insecure, sad and lonely. Leave her and after a few days, u will realise it was the best ever decision taken by you.
