It's not bad wanting your own space at all, don't be too hard on yourself.
I have 2.10 yo twins, they are so demanding, I shout aswell. You wouldn't be normal if you didn't shout, yeh it's best to be calmer, but is that reality? who on this earth is so calm all the time? yeh it would also be nice if we could channel our frustrations other places than at the kids, its finding that place.
How long does dh disappear for, and does he normally come back with regrets and apologies, or does he come back feeling s--t and distant?
How about when he does return, giving him a big hug and saying I'm sorry that you feel this way, and offer him a shoulder, I know its you that needs it, but I'd try anything, even reverse phsycology!
It's probably all about him feeling that he is not supporting the family, not having work. He probably needs the closness of you for reassurance that you still value him as a person.
He obviously doesn't value himself and doesn't like himself at the moment, to feel so insecure to not have his feelings under control bothers him! Perhaps the only way he can feel in control is to have sex, so if everything around him was more secure with a secure job, a regularish sex life would probably perk him up a bit!
Sorry I'm clutching at straws here, I'm just typing my thoughts as quick as they appear, so I hope you can not be so fearful of his return, unless of course you have a reason to be worried.
I'd phone samaritans if things get too bad, you can talk things over, you need to unload some of this upset, especially if you're frightened, they have helped me on a few occasions. They don't judge, or tell you what to do!
