men without jobs are really hard to deal with, i really sympathise for you. it's harder even now, because there are less jobs. your SO might feel (as mine does) that all the news and talk of there being no jobs means there's not even point in looking. but sadly, unemployment affects relationships, and there's little you can do.
you sound a lot like me in your relationship, answering when things are wrong, speaking out, and i know like me you're doing it because you care for your SO, and you don't want things to go unsaid, but sometimes its just not what they want to hear. he's probably getting a bit annoyed at it, and is taking it out on you by nitpicking about your snoring, which is unfair because you can't help that. it is fustrating when he needs to get a job and you can't magically make him get one, and when he doesn't seem eager to look. but that's not something you can do for him i'm afraid.
try to sit tight, and talk things over with him when he's a bit calmer, in a non aggressive way. unemployment does affect relationships but it need not break you up.
