You showed me wonderful things,
Things I will never forget.
I've always wondered if they were true,
But now I see they're not.
You have really good ideas .. But the words just don't impact the way they should . Try bigger ones , incorporate comparisons ..

You made me believe you really cared,
Like I was the one for you.
I've shed those many tears for you,
And now I regret ever shed those tears.
Again with the repetition .. Try to avoid it .

Everyday I wonder how life would be without you,
But now I see how life really is.
It's more beautiful than I thought it would be,
All I have to do is dream about my perfect man.

It could be better . I don't know .. It just seems like it's missing some thing . 4/5

"And now I regret ever shed those tears."
maybe try
"And now I regret ever sheding one."
I liked it. That was the only thing I saw that you might fix. I gave it a 5/5

The middle stanza wasn't too great. Messed up the flow and emotion of the poem quite a bit. The other two were pretty decent. The beginning was strong and the end was okay. I wouldn't say strong or good, but it was okay. How you can fix that? Just go over the middle stanza, reword it a bit and in the last stanza try to mix it up a little. They just need some work. If you absolutely can't find anything wrong with it, just PM me and I'll show you ways you can fix them. I try not to TELL people how to fix them, just give them ideas of what needs fixed.
