Boyfriend blues

Sorry it's long, but I'm looking for somebody to speak truth. 
My man is my rock. He's brilliant, he's funny, he's hardworking, he's affectionate, he's handsome, he's generous. I've only known him for a little under a year, and during that time, he's undergone some difficult stuff. He graduated and has been job hunting, but the job he had for a while, the business closed and he's been out of a job. 
He's been applying places but it's been rough and the gigs he gets have been unreliable. Well, he has been having trouble with rent and food and hated having to ask his parents for money. I told him I could help him out but it hurts his pride if I do more than bring an occasional meal.
He has been really sad for several months and has been staying inside all day playing video games and sleeping. He's losing weight (he's already pretty lean) and losing his sex drive. I have tried to be supportive of him and encourage him and pray for him and try to involve him in activities, but I just don't know what to do. 
Any folks with experience with depression? What would help him the most?
