1.There is something we have to learn to give up.Only without reluctance to move on can we embrace a bright future.
2.I didn't mean to ignore you,I was just trying my best to forget you.So,please try to leave me behind.
3.I don't know how much courage I need to say goodbye to you,my unforgettable lover.第三個不要這樣翻譯 不是我的情侶 換一下。謝謝 好的話就是你了那就換成beloved，表示她/他是你“心愛的人”或者”親愛的朋友“。如果你還覺得程度太深了，就用最普通的 girl/boy代替。
