That is exactly what I've been through. It's painful indeed and it kills me more when I have to keep this feeling between me and myself.
People come and go. That just how they live.
It's my fault for getting attach with them and it's my fault for falling in love with them.
Being loved and falling in love is a whole different thing. Know why? Because whatever things that are falling will end up break into pieces. Same goes with falling in love. Eventually, everything will break including my heart.
