Depression in a a relationship

Lately my boyfriend has fallen really deep into his depression and I don’t know what to do anymore. I don’t know what I can say to make him feel any better. He’s going through a really hard time. The mother of his child is a terrible girl and she’s making his life hard and their child. He’s hating his job and I think just life in general. He’s starting to say things that are really worrying to me and I just don’t know what to do. I REALLY think he needs to talk to someone but he’s not going to do that right now. Is there anyone I can talk to about it to get him help. Preferably something that doesn’t cost a lot of money
