Not sure how to put this but DH and I are worried about our neighbours. Only been neighbours for over a year and they seemed the perfect older middle class couple. Do everything together, always gardening togeteher, walking together. We don't see them that much but are friendly enough and always say hello and have the odd chat. In the past month or so, DH and I have noticed a shocking change. First was when I heard them having a blasting argument, mostly coming from the lady. Just raised an eyebrow at first but since then it has become very common. You hardly hear anything from him but she just goes on nonstop in a really disturbing way. In the past week or so it seems to have escalated and she has been screaming at times and we even heard a few slapping sounds. Their children live overseas so are rarely here and tbh we have wondered if she has some kind of mental illness or dementia or something as her tone and speech pattern are very stange as though she pauses between every word in a monotone. We are worried about how the husband is dealing with either what sounds like spousal abuse or mental illness. I'd like to have a word with him just in case he needs help but it is very difficult to catch the right moment or how to broach it. We have no experience in Dementia or such but wonder if the description above sounds familiar to any MNers.
