He has told me today he sees them moving in together. I have some concerns, he is in extremely poor health, severe heart failure and other problems and she is 14 years younger and in excellent physical health although he told me today she is bipolar. It all seems to be moving very quickly, I haven't even met her. She lives in a council flat, he owns his house. Would she have any rights over his property if she gave up her tenancy and moved in with him? I want his happiness obviously, but I'm concerned about her motives (maybe unfairly I know), and also that he doesn't realise the reality of living with severe mental health issues, she was recently hospitalised and since DH is bipolar I know how ill you have to be to get admitted these days, but said they tweaked her medication and is under control now, which he accepts at face value. I'm very worried.
