I think there's a slight difference between the talent required (to say nothing of the work required) to become a professional athlete and "realizing that love bombing is actually something to avoid rather than indulge in." The latter seems more akin to quitting drugs or alcohol, which "normal" non-professional athletes do daily.

I don't think it's simply genetics rather than actual work (preferably with a therapist) and frankly it seems like you're just trying to minimize my experience with a defeatest attitude. Well, if that's your attitude, you're right you'll never be able to because you'll never bother to try, since you aren't some genetic supermutant who can control things like "don't do heroin" or "don't eat the third cookie," or "don't date the girl who is clearly trying to manipulate you with lovebombing." Is a relapse possible? Always. But does that mean only Tom Brady can benefit from therapy and quit dating toxic people or quit substances? No. Far from it.
