Something being intrinsically motivating doesn't mean it's the only motivating thing.

Good thing I never said that. The question is not "Is there anything a partner can do to make you end the relationship," it's "is there anything a partner can do to affect your desire for their happiness." If your desire for their happiness really is intrinsically motivated, then the answer to (2) is "no." But no-one believes that's healthy.

If you mean logically implies, this also simply isn't true.

"Logical implication" is emphatically not the ordinary use of the word implies. And you know that.

You may want to take a breath and rethink how much of what you're saying you actually believe, and how much you're simply saying in order to win an argument.

I'm not as smart as you to understand which of my positions are so flawed that I deserve to be belittled like that for advancing them. Fool that I am, I believe them all.
