Gf argues over money

I think you need to talk about this. My boyfriend and I don't split down the middle all the time as I get grants and he doesn't, so our compromise is that he pays to come and see me, but I pay for food etc. while he's here. You need to reassess the situation together when you're calm (e.g. say you'd more appreciate perhaps paying less than half for a meal in exchange for her not buying unnecessary gifts).

I think you're both being selfish and childish.

You sound like friends who aren't really that close. If you are in a relationship then there is no need to split all the time, just make sure you pay for a fair few things, as she should do too.

Sounds a bit petty to me.

My other half and I pay our way from one pot. Whatever each of earns goes into and out of one bank account. We don't see it as "my money and your money" it's OUR money.
Big purchases are always discussed, but the little stuff - well that's just life isn't it?

Bigger and better things to worry about IMHO.

Just because she's from a wealthier background, it doesn't mean you should freeload.

I don't see the issue here - it seems fair enough that you should both have a similar financial outlay. Whenever it comes to money between my boyfriend and I, we basically either split things down the middle or one of us pays (usually him) and the other looks for another opportunity to pay for something else so it evens out (usually me).
You cannot expect someone you are in a relationship with to subsidise your life, that's just not the way it works. It's not like you're married - you both have your own lives and your own financial affairs.

That's what upsets me. I don't do that. In fact I always make sure no one takes advantage of her which has happened a few times with others. Now she is effectively accusing me of it.

I called her every cruel name I could think of as I feel so angry.

Explain your situation to her parents and ask them for money?

If you want to do the same activities as her, you're going to have to meet somewhere halfway - which means paying the same amount.

I would feel angry if someone expected me to pay more, just because I have more money. Where is the line drawn?

If you call her names, you're being silly. You can address the problem maturely, if you're rude you will just push her away.

Do you expect her to pay for you? If you can't commit to paying, just say you can't and suggest an alternative. But don't make her pay more.

If it's for necessity, i.e. you cannot afford food, then asking her parents for money would be excusable. But to fund their relationship, no. They're not a cash cow.
