the end of old relationship

after about two years and nine months of relationship, about not too long ago it finally came to end..not that I'm sorry of it, since I'm the one who have chosen that path.. but the sorrow that I'm feeling is because i miss someone so much..i miss his family, the little ones to be exact..two days back, his younger sister called me and said that she misses me so much..she wanted to see me..it kinda broke my heart when i heard she said that..I'm not sorry that it has end, but I'm sorry for the way it end..no matter how much it hurts inside or whatever happen, i couldn't deny that the way we end our relationship is kinda harsh..if i could undo the time, I'll chose a better way to put an end to the relationship..knowing that what goes around will comes around, it kinda makes me scared..scared that when i hurt people, people that i love will hurt me back..come to think of it..better to be careful next time..meaning that, i will try my best not to hurt people..cause i know it will hunt me back in the future..
