没办法.when you love somebody it's very hard to forget it whether we had bad or good past with her. Like me, I want to forget my first love, because it's so hurt enough to remember her. but I can't forget her. so I move on.
in the other hand, I can't forget my second love too, because her kindness and so on. But our relationship had over. even I already have the new one now,I never forget the second, and maybe I'll never forget her at all. But the show must go on, you must use your past to learn for the future.
I think,this is the lesson from God to be learn so we can move on forwardly and be strong enough to make the new step.
祝你好运。
