Poor guy. Honestly his first wife told him (and the world) *exactly* what he was doing that caused her to leave him, and she was very sensitive about it, as well as extremely clear -- she's a good writer. Despite wanting a long-term partner, he's repeated the same mistakes in all his subsequent relationships. They're classic workaholic mistakes: he's spending so much focus on work that he starts treating his partner as an accessory to his work and doesn't compromise on work to meet her needs and desires.
Relationships are *work*. Not as much as children... but Elon deliberately outsourced most of the childcare to nannies (said so himself) and you can't outsource the relationship work.
I think as investors we may want him to continue being a workaholic, but he's never going to have a happy love life until he takes a few steps back to give himself enough time and energy to work on romantic relationships. I hope he manages to delegate enough of the Tesla management soon that he can do that (he seems to have delegated enough of SpaceX).
All his exes are still friends with him. (And apparently with each other.) But they can't have romantic relationships with him unless he's prepared to spend the time and energy on the relationship, and he won't because he's too busy saving the world.
Poor guy. I don't think he understands it.
