Is this fair?

[Chesssplayer]

Me and my partner have been together for 4 years. For 2 years of the relationship we have been living at my parents house to save for a mortgage deposit.
He has just been offered a well paid job in another city and wants us to move there and rent.
However, we have different views on how we should pay rent/bills.
He wants us to pay 50/50, whereas I think we should pay proportional to our income, as he earns significantly more than me. He also said he wants us to split rent/bills this way even if we get married.

Is this fair?

Of course it's not bloody fair.

You're not flat mates.

He's supposed to actually give a fuck about you.

Seems he wants you struggling while he has plenty.

This man wants to save much more than you so he can have a bigger share of the house when you buy one. A man like this is not a keeper. He will be one of those that expects you to pay half even when on maternity leave and expect you to buy all kids stuff and pay for childcare. Just ask him how he would envisage sharing finances in this situation - he will tell you exactly what he is like because he is a greedy cunt and thinks this behaviour is fine.

Exactly

Please do not follow him to the city unless your career benefits from it.

Pay the same percentage but not the same amount.
Add up total bills ie £2,800, then write down total incomes for you both ie person A £2,000 person B £1,800. These two incomes combined equals £3,800.
Now divide total bills £2,800 by £3,800 then use the number you get by each person's wage. It should work out person A pays in 1,473.68 and person B pays in 1,326.32. You have both paid the same percentage and will both have money left over each month individually. That's how I would do it, its the fairest way.

I agree that your way is fairer.

Are you planning to have children with this man, OP? If so, make sure that you carry on working full time and he contributes equally to childcare costs. He sounds like the kind of person who would expect you to take the salary hit from having DC!

No it's not fair. And I'd find it worrying in your position. What if you get ill and are unable to work? Or if you have children are are earning even less? It doesn't sound like he views you as a true partner and I wouldn't be moving to a new city with him under these circumstances.
Interesting that he's been happy to take advantage of living cheaply at your family home...
