Why don't guys really express their feelings? And what am I supposed to do?

Okay so for context me and my boyfriend have been together for almost a year now we live kinda far from each other but he's amazing but my boyfriend is depressed which I knew already so that's nothing new but when he's feeling at his worse he talks to me less I've noticed he says is because he doesn't wanna put down he wants me to be happy and not depressed bc he's depressed but that only worries me bc because I know that he's suicidal there was 3 separate occasions where he told me he was possibly going to kill himself but I don't know if he's actually attempted to or not and yesterday he literally said he said he feels like he's losing himself again and he told me to have a good rest of my day and I was asking him if he was okay he looked at it last night but he didn't reply and I haven't talked them today yet I just worry about him. And then he'll apologize for not talking to me but it's like why are you apologizing for being depressed and I don't know what to do cuz I don't want to force him to talk about something he probably doesn't want to talk about but also I just want to make sure he's okay I don't want to lose him.
