I really have no idea what you're on about. Where is the non commitment here? She literally says she wants to continue the relationship.
Commitment might've been the wrong word. Lack of faith in it instead then. Like I said it's the third time you have to say yes to that question. Why's it have to keep being asked?
First of all it only happens twice, after the Nightsong decision and in the epilogue. Secondly she's obviously insecure after everything that's happened. She has multiple lines talking about how she's undeserving of happiness, her family, her real name, and even says she's not sure how she tricked the player into thinking she's deserving of them.
