A Beating Thing

As is we won't cause her any strife

"As is", or "as if"? If the former, you need a comma after "is". If the latter, it's a reminder to not trust spellcheck for such programs do not always detect words that are spelled correctly but misused.

We've no love, no stories to give her
But she's already brought us together

These two lines contradict each other, in addition to contradicting the adoring wonder of all the prior lines.

She's a miracle in everyway,

"Every way" is two words.

One other thing: what happened to the rhyme in this stanza? It just seems to evaporate. Come to think of it, the rhyming throughout this poem is rather inconsistent. Are you or are you not trying to rhyme? Alternating can sometimes work, and until I started looking for it after that one stanza, the switches weren't obvious, but it's a bit confusing to your readers if you switch between rhyming and not rhyming within stanzas without a clear pattern, and right now, there's no clear pattern to the changes.

I've lost it, but never had it
Will she be my miraculous
Life changer,
Decision maker,
Love taker, in my life?

And then the flow, which was pretty smooth throughout the poem except for that hiccup in the middle, was completely derailed in these last few lines.

Overall, this wasn't a bad poem, but it wasn't particularly engaging, either. To be honest, it was rather bland sappiness, and the worries were so vague because the reasons for them were so vaguely mentioned, they didn't really have any impact on me as a reader.

Try including more specific cases, incidents, images. They'll help reinforce the emotions behind and within your poems. Also decide whether or not you're going to rhyme and, if you do, what pattern you will follow. Rhyming relies on patterns, and rhyming sets up the expectations for patterns; failing to follow through on one when the other is present rarely turns out well.
