Oh c'mon, I don't think asking your daughter to help you not die would be abuse. Purposely trying to manipulate Rapunzel into staying with her and keeping everything the same and not having her own life by saying "I'll die without you and NOPE there's nothing else we can do" and refusing to change her ways or look for a compromise or a better option -- that would be abusive, but just laying the facts out on the table isn't.

What should she do, just let herself die? True, that would be a feasible option, especially given that she's already really old, but I couldn't exactly blame someone for not wanting to take it.
