My boyfriend is suicidal

My boyfriend has really been scaring me. 
He suffers with depression which is something I understand because I deal with it too. He works his ass off and he just wants to get us an appartment but we hit one bump after another and I understand why he feels stuck in life. When i met him he had no license no car no job. I have encouraged him throughout everything. I kept pushing him, He has his license now, a car and a job but he just wants this ONE thing that he feels is so far out of his reach. He gets so stressed out and feels like it's never enough because I swear we have the worst luck and one moment we are good on money and then one thing or another happens to set us back even though we both have full time jobs. his mother called me out of nowhere the other day crying because he called her and broke down saying he wanted to kill himself, I know he wants to kill himself he's told me. He's told me I am the only reason he's still here and I hate that. I desperately want him to see the beauty in himself that I see everytime I look at him. He's an amazing person with this huge heart, he is so worthy of everything this world and this life has to offer and I shouldn't be the only reason he hasn't killed himself.  he just has a lot of hurt and has been hurt continuously his entire life. It's getting worse and he hasn't told me it's gotten worse but I can just see it all over him. I know I can't fix him but I told him he has to stay here with me, for me because I love him too much to let him do this. I just don't know what to do, I love this man more than I love anything in this entire world and I have continuously let him know that I am here for him and that I believe whole heartedly in him. I just feel so sad and broke over this because I feel like no matter what I do it's not enough. I don't know how else to express how much I truly and genuinely love him and that I will never go anywhere. I just want him to be okay.
