She can't read your brain,man! At least show her some love. Make some effort! Don't just abandon her if you want her. So that she know how to take care of her feelings toward others. Which mean, she have to take care of your heart and she know it. That is just after she know that you love her.
Don't leave her clueless. Shes also a human that have heart of feeling. She wont let her tears flow everyday. She keep strugling to live and being happy. The sickness of smiling that only herself feel.

Boy, dont play with girl's heart. Same goes to your partner,wife,sister,daughter and ofcause, mother. Thankyou.
