感谢你，肯把时间花在我身上。我懂得珍惜。

Although is not official, but this is enough. What I have right now, I appreciate and satisfy. I won't ask for more. Since this is what I've point out at the first time. I remember every single thing you said. I'm not giving you pressure. Is just when you have the dream to go for, you'll be happier and meaningful. 

I don't need to spend my time with you forever and happily ever after. I only want to spend time with you until you find your better half. This is not a commitment. Never ever promise something you might break it. Perhaps I've been through a unforgettable relationship. Now, everything seems easy and straight forward. 

We'll see after many years later.
