I have a good relationship with DM but not DF, who was emotionally neglectful at best, controlling and borderline emotionally abusive at worst. Both now very late old age,still together. The problem is my DM is now too old to see me separately - going out is too much effort. So if I want to see her, DF will be there. He's not at his worst these days, but still an unpleasant and unstable man, who can flare up without warning. After a fair bit if counselling, I can be polite to him but would rather keep him at arms length. Anyone in a similar situation? Got any advice?
