Please bear with me as I explain why I believe this.
Genesis 3:12 says:
"And the man said, The woman whom thou gavest to be with me, she gave me of the tree, and I did eat."
I believe the straightforward meaning of this verse, strictly parsed into modern terms, would be something like:
"You made this woman and commanded that she should remain with me. She gave me the fruit, and I ate it."
Personally, to add a bit of the background story, I would fill it out thus - knowing that it is going beyond simple parsing, but confident that it is not wildly speculative or off-the-wall:
"You made this woman and commanded that she should remain with me. That was the first and greatest commandment you gave me. Therefore, when she gave me the fruit to eat, and I realized we would be separated as a result, I ate it also in order to remain with her - and fulfill the first and highest law you gave me. I had a choice to stay with you alone forever or be with her outside your presence, and I chose to remain with her rather than to remain alone with you."
I have read quite a few varying interpretations of this verse, but each of them requires that the interpreter make some core assumptions about the relationship between Adam and Eve - and, in almost all cases, those assumptions are a direct reflection of either our modern conception of relationships, an obvious argument for a particular political or gender-specific issue or a view that simply is not supported by the text itself. As someone who sees the story figuratively rather than literally, I understand differing interpretations, but the one I have outlined is the only one that makes sense to me - given the totality of the account and the initial command to "cleave unto her and none else".
Consider carefully the following point: "None else" includes the Lord, Himself - so, in a very real way, Adam was making the choice we teach that all will have to make in the eternities (to "leave home" and the presence of the Father and Son and embark on our own eternal journey as a united couple - "God" to our own spirit children). Thus, I see figurative meaning in the Garden for both our mortal and immortal existences - and I see Adam's statement in Genesis 3:12 as his straightforward explanation of his choice to accept the Father's full plan, by placing life with his wife ahead of life alone with God.
