You are the only one that I love forever. 我永远只爱你一个人 若有疑问及时追问，满意敬请采纳，O(∩_∩)O谢谢~~
You are the only one I love 其实1楼回答得也可以，但用从句会更深情！可以说：“you are the only one”然后停一下,脉脉地看一着她,轻轻说出“I love”哇,好浪漫哦！
I only love you along all my life. 或 You are my only love this life.
You are the love of all my life! 如果这句都不能让你表达你对人家的深沉的爱的话 我无言以对！！！
You're my all. I will love you and only you for the rest of my life. That will never change
My dear darling, i will love you forever in my life and i won't let you down
I want your heart belong solely to me, from today to the end of our days.
I only love you all my life. 希望能帮到你，祝更上一层楼O(∩_∩)O
