Maybe, unless Alpha needs help and Beta needs to give that help.

unerring instinct? level of unconscious anxieties? mirror their own dysfunctions? trigger their unresolved emotional pain?

These terms to explain just relationships or is he teaching a PhD class? Can he make it more complex than this please?

Seldom after the second bad choice.........

Sounds a bit like a word salad to me. I think people might fall in with someone with their same dysfunctions, but I wouldn't think that is ideal.

What I see with successful couples is patience, understanding and encouragement for each other's anxieties and dysfunctions, each with different strengths and talents to balance each other, provide either more stability or more whimsy which ever might make the couple happier together than apart.

Those are just my observances. I'm no expert, since I am a person better off alone than with a partner, so far as I can tell.

Nonsense.

Perhaps it is one aspect of attraction, I don't see it as the sole one.

Marriages succeed and/or fail for a variety of reasons. There is no single explanation in either case.

Nah, been married twice, and divorced twice. Nuf said.

I have a lot of time for Gabor Maté. While it may not be true for all couples, I see a lot of truth in it.

Codependency can be a bitch. (Been there, done that, finally escaped when I recently killed the three demons inside my head.)

Schema-based cognitive behavioural therapy is an escape route from the prison of unresolved emotional pain.

a convoluted answer. but yes, opposites attract

I think this is too academic. To me, couples want to find partners who have similar likes and views so they agree on things and enjoy life together + accommodate each other on the way.
