I think that the Genesis account could exclaim the strong emotional bond, but unfortunately we don’t get a sense of what strong emotional bond Adam and Eve had. .
They made Love; God does not permit lust, therefore i would say that this gives us a good sense of a strong emotional bond; Adam and Eve must have been married in God (Having permission; although obviously not in the same way we see today).
You mentioned Adam’s declaration that this is “blood of my blood.” In those ancient cultures, blood along with breath, were symbols of life.
A soul is what makes a person a person, rather then an impersonal-animal. It does not make sense to me that God would make Eve out of Adams personal soul, for Eve would then be Adam, rather then an indivisual, and i dare say that this would be agains’t her will; which in turn is agains’t God. This is why i say that these very “strong words”, words that have been used in a different sense (as you have stated), quite possibly could have been used as a simeli to show the fulfilling of Adams yerning for an Eve.
“Finally i have found my bride— she is my life”.
This is just an example of how somebody could play with words to express something profound; and i think that we have every reason, when looking at the bible over-all, that the various authors purposely employ such word-play through out the narrative, in order to get a profound and deep meaning across, and an emotional response from your soul.
“God parted the sea with a breath of his nostrils.”
I love word-play such as this; it makes the bible so much more deeper and inviting. At the end of the day, the authors where “entertaning” as much as telling a truth.
As far as Genesis being used as a way to react to certain heresies, I have seen no evidence of this.
Well there are different creation stories; such as the one where God splits the dragon in two; thus the universe, including us, was born out of the dragons blood. And this is the reason why we are sinners.
The Genesis story could quite possibly be a counter reaction to the heresys and errors of other creation stories, that may have been imposed on Jewish slaves and captives.
And then there is the matter of giving God at least one day of worship; making a holy day for God; the sabbath.
And then there is the sin of Homosexuality.
For these reasons, i can see the neccesity for the Genesis creation story. However, one cannot prove that it was for these reasons that the Genesis story was created; it just seems reasonable to me.
