But if he wants to keep you, he'll have to propose to you. (Under duress, CAC, so don't expect a flashmob.) If he doesn't want to propose to you, he loses you.
Dan Savage @45, I know you've advocated that women can be the proposer
. That is why I cannot fathom why you gave the advice you did. She can propose an engagement. He can accept or decline. She can then decide if that is a deal-breaker.
But to advise that she insist on a situation wherein he proposes "under duress" is ludicrous and sexist. Unless you meant that he should propose, she should accept, and he should secretly void the engagement in his head to placate her...which is just bad advice.
