wat does it mean??

All it means is that you have love for somebody. It could be a true expression of love, or an expression of fear. Fear that you love him still, or maybe fear that you don't love him anymore, and he was part of your life. If you are at peace with being apart, you having nothing to worry about. It's just your brain expressing things that you feel. Think about yourself. Has the person that you are changed since he left, and do you not like yourself as much? Breakups are more about yourself than you think.
