why is it my 70 year old father will only date women age 50...

Why is it my 70 year-old father will only date women age 50 or below?  Most of the women he meets (on the internet) are just out for the take or looking for some place to live. He is spending countless dollars on these women paying rents, car payments, taking them on vacations and buying their kids stuff while he refuses to help his own family with basic stuff like light bills or dorm payments.  When we confront him about "these nice ladies" he tells people we are jealous and worried about losing our inheritance. He uses terms like "we are going steady" or "she's had a hard life and needs me."  He met a nice lady who was 71 but to him, she was "to old" (about a 5 month age difference-but she is to old).  I live alone with my children and have a hard time making ends meet.  When I ask for help, he will suggest either going to church (give 10% and God will give you back a million-I dont believe in that) or meeting an older man so that money will not be the issue for me.  Sounds like prostitution to me.  He's even gotten involved with "Asian wife finder" deals.  I am at my wits end trying to tell him that he is not the "cat's meow."  I stopped taking out the "trash" with these women for him.  It's terrible- is he crazy?  He acts like he's 17 years old.  He will cry over them when there is breakup, throws tempertanrums and is over-sexed.  He even hit his 15 year-old granddaughter in the face with a suitcase because some woman told him it was "over."   What do I do?  How do I protect myself and my children from him?  We do not want to get stuck with the credit card bills he is running up after he dies.  We don't want his stupid drama and sure as hell don't want these "nice women" starting crap with us.  He promises to "write them into the will" if they are nice to him.  The "Asian wife" and "Russian wife" things are a nightmare.  He also laughs and tells me that he wants to die with the last dollar in his pocket and strap "his kids" with the debts.  He didn't even raise us.  We raised ourselves.  He left when we were little.  I am just sick of the drama and tired of getting blame for "breakups" and his unhappiness.
