Any advice?

So I'm in a long distance relationship with my boyfriend, he lives in France and I live in the UK. We haven't told our families about our relationship mainly because they don't live in the same country and we're not sure about how they'd react. My boyfriend has depression and occasional suicidal thoughts. Last night I tried to console him with supportive texts, but he told me to leave him alone, and that he doesn't have a future and doesn't know why he is alive. I'm heartbroken by this, I just want him to be happy. He refuses therapy because he doesn't like people, which is unfortunate. It's been 1 day since we last spoke. I'm scared he has hurt himself, or worse..but there's no way of me knowing. Sorry this is a depressing topic. Any advice? x
