I'm so silly...

I know it's not my business. It's totally got nothing to do with me. So why am i being so silly and get so upset then? I just feel like ,why things have change from the way it used to be? I really thought that they make a lovely couple. They show me the real meaning of love. I really feel that they are meant to be for each other. However, they split after so many years together. At first, i find it hard for me to accept it. And now, she is married, with other guy. Maybe everyone does change. Only me, stay at the same point, can't accept for any changes. sigh....
