Thats pretty eff-ed up that you wouldn't help out your own husband if he needed to find a job. I mean he helps you with the rent/food/utilities right? I dont agree with what OP did you don't have a valid argument either. Also I dont know where OP lives, but you can walk around in small towns. In large cities you wont find avaliable jobs blocks away from each other you need to drive because they are far.

Walking is not always a viable option for most people in bigger towns or cities. What if OP is looking to get a job in a certain profession? That would also limit his options. Not everyone lives within a 20-30 minute walking distance of several big shopping centers or malls. My usual 10 minute drive to work would take at least an hour to walk there if not a little longer. I'm not saying what OP did was okay, it's not. But it's also ridiculous to tell OP to walk everywhere to look for a job. Taking the bus would be a much better option. Besides, it's tiring enough to look for a job without having to walk absolutely everywhere you go.
