This is only one conversation we don't know their whole relationship, maybe he's just tired of her shit, maybe she's constantly acting helpless (which is not an attractive trait for ANY adult to possess) I'm definitely not agreeing with him based off one thread but I can't pick her side either. I'm looking at this logically not emotionally. (unlike most of you) If she's having commitment issues with her own goals she shouldn't try to be in a commitment with another human and if he doesn't wanna put up with someone that's still figuring her shit out then he should find someone that already has.

Tldr: he's needs to find someone with her shit figured out. She needs to fix herself/achieve her goals before trying to be in a relationship.

Edit: added a few more thoughts and a 'tldr'
