等到永远 meaning in Chinese

and wait forever more

Knowing you fear to face the parting , i don ' t dear to see you , don ' t dear to see your eyes , until i get on iron horse , the music of piano make me fell more distressed , also i fell so happy before you , but just in appearance , now i cannot help my tears , i feel helpless , don ' t want you sad , i think we will not leave each other for ever one day , you said you will treasure me for one life because you love me !
知道你怕离别的伤感，下地铁的时候，我不敢回头，不敢看你的眼神，直到冲上火车，车厢里响着悠悠的钢琴声，让我此时的心情更加伤感，一路上和你嬉笑怒骂，表面坚强的我忍不住泪流满面，不愿你难过，我想我们一定能等到永远在一起的那一天，你说过，爱一个人就要珍惜一辈子的，对吗？
