Today started well. Morning not to bad. I had to wait in for cooker repair man who would be coming between 12 and 2. Also Crossroads chap coming 1.30 til 3.30. Cooker man arrived after Crossroads chap so in the end I didn,t go out but spent the time talking to sitter and husband chipping in his bit of 'nonsense' that didn't follow the conversation. Our Crossroads sitter is very good at conversation and trys hard to keep husband in the conversation. After he had left husband started to pace. Like switching him on! This went on for 2 hours. I had gone into garden to get washing in and when i tried to get in the back door husband was blocking the doorway. I said 'Will you stop blocking the doors all the time. As i tried to get through I stumbled and nearly fell. As I got my balance he swiped out at me and hit my arm quite hard. I was shocked and it hurt. He said sorry but I am now worried, as he has been getting more and more angry lately. He has always been a calm and patient man. I know that dementia can make people change. Does this mean that he is going to become violent. Can anyone advise me.
