I'm very worried about my Dad, he's 83 and in advanced heart failure with multiple other health problems. Mum died 4 years ago and he's joined various things and made new friends which is good obviously, but he's recently started a relationship with a woman in her late 60s who is young looking and fit for her age and seems to have been the driving force in getting the relationship off the ground and onto an intimate footing. She has bipolar disorder and has been hospitalised for mania within the last year. He seems to have completely lost perspective and is acting a bit inappropriately, clearly flattered that apparently he's still capable of attracting a much younger woman, yesterday he showed me a photo she's given him ( after he's spent the night with her over the weekend), and she's in a swimsuit! I feel guilty that I'm having such strong negative feelings, I know he has a right to live his life, but it just feels so wrong, and I'm angry with him that even at his advanced age it appears his brains are in his pants. And I'm worried sick she's high and it's all going to go horribly wrong.
