Leaving Me Crying

Hello. Firstly, I just want to say that this is a really beautiful piece. You included description with your emotion, and couldn't have made it any clearer to the reader the level of heartbreak in it. I'm sure that many people have suffered a heartbreaking story like this, in some way. That is another reason I liked it so much. You, as the writer and probably the feeler, have made it accessible to any reader. They can be drawn into it, and appreciate it like it should be appreciated.
However, with all that praise, there were a couple things that I noticed, that if it were my poem I probably would look at some more and contimplate changing. (Though, saying that, I also realize that most poetry is done for certain reasons, and changin' them later means that they may lose a small part of the meaning they once held for you. So Please don't take it too personally, it is simply my personal opinion. Some others may not agree! And you are the writer, not me, so please do as you feel is right - even if that means disregarding every single comment I owe you!)
One thing I noticed: in the first stanza, your last line is much longer than the rest, and almost -not quite, but Almost- takes away from the rhythm. And I think that 'iambic penatmetre' works better when you seperate your words, rather than using the more modern day approach- putting that apostrophe in.

I find myself crying, though you're still here.
One day you won't be, and that's my greatest fear.

Before goin' on with more criticism, I want to note that I absolutely loved this line:
So I soak up the moments I still have with you.
And regret the ones I lost when I had better things to do.

However, the line after that seemed a little bit more forced, in the sense that it seems you put the word 'even all the more.' in there simply to add another syllable and keep the flow. (Many people do, and I won't deny, I am the majority of those people lol. So no worries, it still worked, but as your temporary critique, I owe you what you earned in that contest - and that's my nitpicking comment. (Aswell as so much of my praise.)
You have:

I know there are things I can never make up for,
And still you loved me even all the more.

and if it were my own, I would probably change it to something more...:

I know there are things I can never make up for,
And still you found forgiveness, and loved me even more.

I loved when you got into the question making, it was really well done and showed the uncertainty and pain all in one hit. Though, I would probably make, another minor change here:
This only makes it harder to accept that you'll be gone.
How am I supposed to get up and keep moving on?

Again, from the point earlier, I would also take away some (not all - just when it's possible) the apostrophes and simply put both words as individuals...For example right here:

For all of these years, that been you.

And that is the end of my extreme pickyness (which I hope you don't mind - I know that, I as a writer, appreciate the harshly critical ones more than the others.) I just want to mention the other favourite lines of mine that were in your poem:

How many I love you's can I fit in before you go?
There will never be enough, and sadly this I know.
For the sake of my heart, and the thoughts in my mind,
I'll say I love you, one final time.

That's right. The whole last bit. I loved it. Infact, I'm so jealous you thought of it before I did. hehe ;). I give you so much praise for this poem. Even though it may not seem that way with all the criticism, I really did love your poem. I looked hard for the things I noticed because I didn't want to leave you with the same old 'good job' comment. It was an excellent poem and I hope you believe me when I say that. :)

This is beautiful! & I love how you explain how you really love him and how he is hurting you..It is very descriptive and very emotional! I love it!
xoxo
