Hi, gsom, and welcome to Psych Central! I would have a hard time putting up with his short temper, too. And you say he wasn't that way earlier?
Does he have any relatives who might be able to tell you about him? Maybe he managed to keep this temper hidden while you were dating. It is possible, though, that he is depressed.
If you can, then you might consider talking to a marriage counselor. I'm not sure he would go, so you might go on your own.
Have you tried telling him how he makes you feel when he is so short-tempered? If you are careful in how you word things, then maybe he won't go on the offensive so much. For example, why does he get upset when you leave the iron box plugged in? Can he explain that? ("I am wondering why you seem to be bothered when I leave the iron plugged in. It hurts me when you get so angry at me.")
It doesn't sound like he has a job. Why is that? It could be that he is bothered that he can't be "the man."
Maybe something I said will be helpful, anyway.
