Men vs Women

Her diary:  Tonight, I thought my husband was acting weird. We had made plans to meet at a nice restaurant for dinner. I was shopping with my friends all day long, so I thought he was upset at the fact that I was a bit late, but he made no comment on it. Conversation wasn't flowing, so I suggested that we go somewhere quiet so we could talk. He agreed, but he didn't say much. I asked him what was wrong: He said, "Nothing...". I asked him if it was my fault that he was upset. He said he wasn't upset, that it had nothing to to with me, and not to worry about it. One the way home, I told him that I loved him. He smiled slightly, and kept driving. I can't explain his behaviour. I don't know why he didn't say, "I love you, too". When we got home, I felt as if I had lost him completely, as if he wanted nothing to do with me anymore. He just sat quietly, and watched TV. He continued to seem distant and absent. Finally, with silence all around us, I decided to go to bed. About 15 minutes later, he came to bed. But I still felt that he was distracted, and his thought were somewhere else. He fell asleep; I cried. I don't know what to do. I'm almost sure that his thoughts are with someone else. My life is a disaster.

His diary: My code is broken, can't figure out why.
