Goodness I only just worked my way through all your comments and suggestions and must say I feel overwhelmed by such kindness and concern. Apologies for not responding to all the points, the majority of which lead in the same direction and give me a good deal of pause for thought. I am very grateful for the advice about him being a lodger not a tenant - I was thinking of a tenancy agreement because he also has his eyes on my mother's flat (now left to me since she passed away in March), saying that he gives me enough money for us to use both places!! I thought of asking if he wanted to be a tenant in that flat, but he has rejected that idea in any case. Somehow everything becomes skewed when I talk to him. As some of you have suggested, he is a very anxious person (bullies often are) who hates being alone and is afraid of taking responsibility for himself. Unfortunately I am not a confrontational person (as you have guessed!) though I do suddenly snap when pushed as he has done when we have rows about the 'situation'. The hardest part is actually starting a conversation because it inevitably turns sour. I do also still have feelings for him and would like this settled amicably - it's hard after all these years and at a certain age to cut him off and he has said that if he leaves the house we can't be friends or have a relationship, so I am loth to make this final. It does seem odd considering that I never signed up for us living permanently in my tiny house - and only reluctantly let this happen on the basis it would be temporary until his finances were sorted out (money from the sale of the parental house and then from his father's will). Speaking of which, I am sure he doesn't intend to leave me anything (he has a son and three grandchildren) and I am definitely not leaving anything to him, though again this subject is taboo. Loved the article about Fay Weldon btw - I had heard about this but not read the details. Good for her - and that she has loving children. Thank you, thank you all so much - I will read and re-read your comments and take further advice.
