No, that rings hollow to me. Humans are sophisticated enough to genuinely have other needs aside from primal mating urges. Self-actualization is a huge one and more than sufficient to be the primary motivator for someone seeking to leave a family/marriage situation.

And yet, statistically, very few people have self-actualization urges beyond using them as a means to attract a mate and reproducing.

You say statistically but you don't have any references to support that statement. My anecdotal experience says otherwise.

Few, not zero.
