<human>: Give me the gist of the text in a nutshell

My boyfriend gets regularly depressed. Maybe once a month, for what he says is no reason at all and is just hormonal. He says he has thoughts like walking in front of buses, and he tells me this nonchalantly. He thinks it's no big deal, he doesn't need help, and he'll feel better in time. Always does.

He's always cold and callous when he's depressed like this. I told him I felt like he didn't want or need to talk to me when he was upset and that bothers me. And he replied he's "not in the mood to cater to my needs."

He gets irritated when I tell him that I feel unappreciated, and he brushes off all my efforts to make him feel better.

I don't know how to deal with this really, and I want advice.

I'm angry more than anything, because he's so rude and inconsiderate even though he's 100% self aware. He knows there is no logical reason to be depressed, and he knows exactly what words and behaviors upset me, but he completely doesn't care. And he doesn't think it matters because it'll all be over soon! But it always comes back! And every time, he treats me poorly.
<bot>: Boyfriend gets bouts of depression, and gets even more upset when I tell him how his behavior affects me. ( I usually make my titles a synopsis of my problems.. soo..)
