I have what may seem like an odd question. But I'm coming to the point of wondering what is reasonable to expect or want to find in a significant other when it comes to dealing with my mental health?

For me I suffer from depression and anxiety. And I fell into a deep hole of depression recently and am digging myself out. However during my bad days my S.O. wouldnt really talk to me because he said I bring him down also, offered no comfort of even just being there like being close, no checking on me. It felt like if I'm doing good then I'm wanted if I'm doing bad then I'm on my own. He even asked "How often do you get like this?" It's like I can't give you days on a calendar or predict it. I can't cure it. If there is an off switch please tell me.

So what is reasonable to expect from significant others during the rough times?
