why is it my 70 year old father will only date women age 50...
The writer doesn't say whether is a man or woman or if working. I would suggest that he/she start living for self and children, get a job if not working or apply for assistance if can't work, and let the father go his own way and try not worry about what he is doing. I know it must be frustrating and hurts, but it's not like he was ever a part of their lives anyway, according to the letter.
Its obvious he is at a crisis in his life. He is already old and fears it. Women his own age only remind him of how old he is. Anyone woman 50 or younger is definitely NOT interested in a man 70 as far as a serious love relationship. From what you described its all about USE USE USE and he is being used big time. If he's also looking for "Russian" or "Asian" then all the more USE USE USE and we all know those women want their citizenship papers. Somewhere inside himself he must know this. Unfortunately if he is of sound mind you can't do anything. Sometimes reverse psychology works. Don't get involved, don't make comments, when he gets his heart broken just "I"m sorry dad, hope you feel better soon". Try that tactic. Good luck.
Why are you worrying about his behavior? If he dies with debts, you have no legal obligation to pay them, but some "common law" wife just might. His money is his money any way, and you have no right to tell him how to spend it, or to complain when he doesn't spend it on you. He is an adult, after all, even if he is acting more like an 18 year old. My guess is that the poor guy is lonely and afraid of aging -- most men are. He probably feels younger and more virile if he can get the attention of someone 20 years younger than him. That's an insecurity you can do nothing about, so you have two choices: (1) resign yourself to the situation and either live with it or remove yourself from his life; or (2) lovingly try to get him into counseling. IF he is a religious man, perhaps, he'd listen to a minister or priest. Praying and going to church yourself wouldn't hurt, either.
