What an utterly bizarre 'relationship.' I just cannot fathom being part of such a screwed up set-up. 
I would expect this to be the situation if a couple have been together 3 weeks.
How can a relationship function, let alone blossom and grow and develop, when the couple cannot, and DO not communicate, and have utterly separate finances, (eg, making their partner go without, when they are earning more.)
What is the point of being together? 
I actually KNOW a couple like this. Together FIFTEEN YEARS, totally separate finances, he earns double what she earns, and he doesn't give her a PENNY of HIS money.
When she runs short, he lends her a bit (a tenner or so,) and makes her sign a chit to say she will pay it back. He has £45K in savings, she has £1600, they have separate bank accounts, and they have separate cars. When hers packed up, he would NOT let her use his.
He has a house he bought 30 years ago, (mortgage paid off 10 years ago,) and he rents it out. All the rent (£900 a month) goes to his bank account.
He will not marry her. He will not buy a house with her. They rent a small flat together, £400 a month and SHE pays half that, so he is quids in with the £900 rent for the house he owns.
I do know several other couples like this.
The OP's set up sounds like this.
I would sooner be single. I simply cannot fathom what the women are getting out of these relationships. And it is always WOMEN getting the shit end of the stick, because in most cases, the man is the higher earner.... PLUS, no man would stick in a relationship with a woman who treated him like this.
Seriously, what the actual FUCK? Why do these women stay? Serious question.
