He's 70 years old, of course she's in it for the money.
A 70 year old may not be filthy rich, but he more than likely owns his house and has shitloads of savings.
If they get married, she'll own that house and his life's savings when he kicks the bucket.
How good shape is this old guy in? It's very possible he's too old to be having sex i. e. his plumping pretty much doesn't work anymore, so she likely only has to cuddle and kiss. A young little thing showing affection to a man one foot in the grave is probably making him extremely happy and she doesn't have to do much either.
I'd only believe it was love if the guy was broke and living in a nursing home.
Jesus Christ... Look I don't want to call your sister a gold digger... But... Why would someone who was 18, barely the legal age, interested in someone who was 65? Someone who is old enough to be their grandfather. He's old enough to be thinking about which nursing home he wants and she's probably still thinking about what career she wants. These two people are at two points of their life so different that you wonder what about each other could they possible want? Well I can tell you one thing. He wants a hot, young piece of a** to make himself feel young. If she's not in it for the money, what could she like? His long, old, wrinkly, barely functioning yogurt slinger? Doubtful. If she's not in it for the money, which, even though he's not rich, doesn't mean there isn't money for her there. Then she probably saw it as some sort of taboo Romeo & Juliet fantasy and she sees it as an accomplishment. Overall, I would question her decision making skills. I'm 18 right now and the biggest gap I'd go is 2 years younger or older. So to me 47 years is about as disgusting as it gets. I mean, picture her as a 10 year old girl. Now picture the 10 year old version of her dating a 57 year old man. Yucky.
This is rather gross and excessive. And it's virtually impossible to be physically attacted to anyone that age. He must be rich, and if not: 1. You're either a troll, 2. or your sister has some sort of mental condition, sorry to say.
"My sister is white, she's dating a guy that is black?"
Do you see any difference in the questions? I don't.
See, YOU get to decide who YOU want to date. You do not get to decide who other people want to date. What she sees in him is between her and him and nobody else. If she enjoys his company and he does not beat her, then be happy for her.
Age doesn't really matter you know. If she feels comfortable and loved when she is with him then why care how old he is? Being her brother you would be happy if she is right? If you're worried then talk to her about how you feel. It can happen that she might change your mind or she would think over some of your suggestions. Apart from that just let her live. She knows what she wants and you have to trust her and give her that freedom. And even if it happens in future that she might be wrong about this person, you still have to support her as anyone can make mistakes and if you love them then you would support them no matter what.
My roommate's sister married a guy who was old enough to be her father, almost grandfather. But that was because she had an affair with him and got pregnant. If it weren't for some reason like that then God only knows what is wrong with your sister. I mean that is just plain disgusting. And the guy is disgusting for doing it. He is probably enjoying having some young piece of ass for him to play with during his retirement years.
It's an uncommon fetish and it's mostly seen in men but it is possible that she gets sexually aroused by a really old man. It usually happens because of "daddy issues" or a traumatic experience where she is sexually aroused by a "mentor" type of person, such as a professor, a step dad, or a grandfather
Nothings wrong with it. Some women such as myself are naturally attracted. Lucky for her he's not rich! Lol its stressful when they are older and well off as assumptions are made and nothing you do changes the frivolous assumptions. Anyway there's nothing to worry about. he's older sure but age doesn't define love. Dont give her trouble. shell later resent you for it if you go too far
