Are you writing poetry, or do you want to know how to say this in a conversation or a letter? No one speaks or writes using Albert's prose (and some of it is slightly incorrect in meaning). Try: 1 以后你会不经意地想起我，请别忘记我曾经那样深深的爱过你. After you've stopped having feelings for me, please don't forget that I once loved you very deeply. 2 我生命里的温暖就那么多，我全部给了你，但是你离开了我，你叫我以后怎么再对别人笑 I only have so much to give in my life - and I gave it all to you. But, you still left me. How could I ever again smile or laugh with another? 3 你永远也看不到我最寂寞时候的样子，因为只有你不在我身边的时候，我才最寂寞。 You never see what I'm like when I'm most feeling lonely. Because only when you're not at my side, do I feel so alone. [if you said something like this in English, it would make someone vomit. Actually, if I said that to my wife in Chinese, she'd probably vomit too] 4 最浪漫的三个字不是我爱你，而是在一起。 The most most romantic words aren't "I love you," but "together forever" [not a literal translation, but captures the essence of what you are trying to say - Albert's translation is good too, and also not quite literal]
