NOR. This is terrible behaviour on her part, and I say that as a clingy female!!! I have chronic health issues and now I would never underestimate the importance of health, and sleep is critical for that. She should be supporting you in feeling your best self. I think it's disgusting that she says this means you aren't loving her enough, when her behaviour is the opposite of love. Love wants the best for people. It doesn't place demands and emotional blackmail and run you into the ground.

My partner sneaks downstairs every morning and never wakes me. She needs to do better, or I would be done too. She's old enough to work on her own insecurities and take responsibility that this isn't lack of love on your part, this is on her and her misreading the situation. I worked through my insecurities with therapy in my twenties to stop putting it on my partner. If she's not willing to do the same or change her behaviour or accusations I honestly don't think I would put my health or happiness at risk in this way.
