It's a knock to anyone's confidence to be unemployed so treat his feelings with care. You should definitely ask him how his day is, even if he does nothing all day. Be sensitive to the fact that he may be going through something right now, as a man! Even if he acts like it doesn't bother him, the blow up over rent shows you that he does. Tip toe around him and use kid gloves when you talk to him.
In the mean time, it never hurts to give him leads. Be enthusiastic about prospects that you come across in the paper or online that may seem promising. Give him a list of these things and boost his esteem by being supporting and understanding.
Here's a way to think about it. Imagine that you're an overweight woman that gained 50 lbs really quickly over the past six months. The depression and isolation that you would feel (the silent stares, people thinking things about you..."She must eat all day, she needs to put down the candy bars" for him means "He's lazy and did nothing all day...") is the same that he is probably going through. When women are overweight the men in their lives can't bully or chastise them into losing weight. It only makes them defensive. The same with men and jobs. Even if no one says anything to him about his unemployment he still feels that people are watching and waiting for him to jump back on the horse in a critical, chastising way. He has to make the choice to find employment on his own the same way a woman has to want to lose weight on her own. Doing it for someone else or because of ultimatums only makes him resent you more!
All I'm saying is to be supportive and caring to his feelings. Make suggestions and even offer to take off work to go with him on a job hunt to a few places. Be warm and understanding whenever he is upset about finances. If you truly love him, you have to patient. He would do the same for you if you were going through something, I'm sure.
