Why Would A Husband Suddenly Want A Temporary Separation?

I heard from a wife who said: "I will admit that the last year of my marriage hasn't been our happiest time. My husband's parents both died in a car accident earlier in the year. My husband and his siblings fought about how to settle their affairs. This year has been so painful and stressful and our marriage was strained. So I knew that things weren't ideal between us. But I was completely shocked when my husband sat me down and said that he 'wants to separate for a while.' I asked him what exactly he meant by this and he told me that he just feels that he needs some time to himself to sort out what he's feeling. I asked him if this meant he was going to see other people or leave town. He said no to both. But he wouldn't be much more specific than that. He won't give me any concrete reasons as to why he's doing this other than to say he needs time. I don't know how I'm supposed to respond because I just don't understand why he's doing this. What reasons would he have?"
