You will probably never see this, and you will probably never know... 
But... 

天が下のすべての事には季節があり、すべてのわざには時がある。 

I am sad that things ended up the way they did...
I am grateful for all the smiles and all the affection that you have given me...
I am sorry if I made you feel like I didn't care at all...
I am regretful that I couldn't say what I truly felt...
I am angry that you did what you did, but I also understand why you would do it...

But most of all,
I am glad that I got to meet you
And wherever you are, whatever you are doing... I just wish you all the best in life. 

Thanks for the conversations and memories, but like all good dreams, 
I guess things must come to an end, 
You will always be a special person in my life.
