This was reworked, as promised...

Well, hi again.

My first suggestion comes from a personal bias; I have always felt that a poem is either punctuated or not, and that if not, there should be a solid reason.  I think you have a solid reason, poetically, so I'd like to suggest replacing every comma with a line-break, since you have decided to let go all other punctuation marks aside from a full-stop after a very long sentence, one other a short time later, and none at the end of the poem.  I think you have a decision to make, here...but again, this is a personal bias.  The poem and the decision are, of course, yours.

I like the juxtaposition of passion and pathos, and how that pairing accentuates the pairing of roses and thorns.

"emotions borne of the past" may have a double meaning that I'm missing, but otherwise, emotions would be born of the past.  'born' has reference to birth...borne is the past participle of 'bear' as in to bear a burden.

There's a wistful quality here that is hard to escape...hard to even want to escape.  It's pleasantly poignant, front to back, and the alliteration is applied with a delicate touch that makes it all the more worthwhile.  My only other quibble would be to suggest that the phrase 'pregnant with possibility' may have passed, by now, into the realm of cliché, but this is a very worthy work, nonetheless.

Cheers!
