Dh and I have been married for over 20 years and our relationship has drifted over the course of it. FIL has potentially just been diagnosed with dementia (like his mum has been a few years ago). Sister in law has been caring for his mum until her death. Obviously this diagnosis is terrible news - his father is already in a home. However, I realised that I just dont know what I should say or do. I have realised that we have compartmentalised our life. DH usually talks to his sister about his parents' care, his colleagues about work and we usually talk about kids and household. It's same for me. We both work and have busy lives. Is that unusual that we are only each other's go to person when it comes to certain things but not everything?
