Him spending money on stuff he can afford is different than her spending money on stuff she can't afford.

Take a step back. Read my other comments. Stop taking this personally.

If this situation doesn't suit her, she should suggest they live separately. Her current decision - to pay a rent she can't afford, taking loans from her SO, making promises she can't keep, having a debt = bad finances. Bad financial decisions lead to this, she's 27 not 17.

He's spending money on a boat he won't use, but he's still very financially secure.

Guess what? Some people can spend more money than others and still be ok. It's not that novel of a situation.

And unless they're married, and both parties feel ok combining finances and signing that legal contract that is marriage, it doesn't mean jack shit that he has more money than her.

My exs dad was a billionaire. He really liked me. And she had a credit card with no limit. I could literally buy anything, go anywhere, do whatever I felt like on her dime and no one would care. No one would notice. We dated for 6 years - we broke up because of the fact that her business was in her home country and I wanted to make my living in New York.

I never borrowed money from her. I never took advantage of her wealth. Now, they took me on some vacations and her dad convinced me that he'd like to ivest in my fund.

But really, all in all, I saw 0 of her / her dads money.

We weren't married. We dated 6 years. I can't be financially irresponsible because she could buy a fucking yacht (she didn't, she did buy beautiful shoes that were thousands of dollars). I couldn't point to that and say "she did that! So I can spend on what I feel like too."

That's what you're telling us here? He's making decisions that are irresponsible for her?

Because personally she's being very silly. You claim she is paying high rent because of him. I see - so she agrees to a rent with him, suggests she can pay more later on in fact, she never actually pays that amount ... Rather, she needs him to cover her regularly , after he covers some of their social activities...

And still, you think she's totally responsible? What are you getting at?

Have you read my other comments? Hers? Be sensible, she's being pretty blasé here about her finances (and her finances - she seems fine with him quitting his job! What?! Why? Because he has 20k in the bank and a wealthier family than hers?).

She needs to get another job, pay off her debt, get on her own damn two feet - she's an adult at 27 years old.
