Over the last few days, I keep catching him crying. He says he is having nightmares a lot, and when I ask what is wrong he says it’s a long story. He is also treating me like I am the enemy and being quite nasty towards me for absolutely no reason. He doesn’t like his job and finances are tough at the moment. I just can’t work out what the problem is. Living with him is unbearable at the moment. I having done anything to give him a reason to be so cruel and nasty towards me. He won’t talk to me and is very bad tempered. What should I do?
