My dad wants female companionship or possibly more. He has recently found a female friend. She is 47 and he is soon to be 80. Whilst I am fairly liberal, I can’t help but wonder why she wants to be friends with such an older man. He has told me they go out often and from what I gather he has paid about 70/30. He is very generous with his money, but is in no way wealthy, but has a reasonable pension and owns his own house. I would like nothing more than it to be all ‘above board’ but I worry about him. We are taking him out for his 80th and he has told me that she would like to meet me and my brother. Obviously I would like to look into the situation as I am concerned there may be something more sinister. Am I overreacting?
