<human>: Can you give me the gist of the text in a nutshell?

I've been with my boyfriend for six years, and lived with him for four. We have a lot of fun together, and I feel like we're both very supportive of each other. Except when it comes to my depression.

I've had depression for about ten years. I'm not on medication for it and I'm generally doing very well these days. But I'm still not strong enough to handle long arguments or mind games so whenever my BF and I argue, I try really hard to explain things calmly, tell him what I need or my perspective, tell him when everything starts getting really difficult to cope with. I'm definitely not perfect, I can snap at him and I wish I didn't. But no matter what I do he always responds in the same way.

1. He gets frustrated and angry
2. He sits silently ignoring it, which hurts me the most (I've never understood why it makes me feel so worthless)
3. He blames me for everything

I can't handle those things. It goes on for hours and it's so draining. I keep asking him to stop when he's like that but it only seems to end once I've reached the point of utter hopelessness. Sometimes he even just disappears, leaving me to deal with it alone.

I want him to communicate better because his pattern seems to send me into a spiral that's so difficult to claw my way back from. But is it wrong of me to expect him to recognise/change his behaviour because it may have an affect on my mental well-being? I don't want him to ignore his own feelings, I just want him to communicate them in a healthy way. Am I being selfish by expecting that my mental health is a priority even if we're arguing?

He told me once that he expects me to "just get over" my depression, but that was years ago and since then he's become much more understanding/supportive of mental health issues. I keep thinking that if he became more supportive once, he could do it again, right?
<bot>: BF's pattern of ignoring me, getting angry and blaming me in arguments is negatively impacting my depression. Is it wrong of me to expect that my mental health is a priority even if we're arguing?
