I've lived with my girlfriend for over two years. When we were talking about moving in together we agreed that as long as we could both comfortably afford 50% of the rent and bills then that's how we would split it things no matter what the split in pay was.

By comfortably afford we mean afford it while still having money to save and have disposable income for the month.

This has been fine for the duration of us living together, we've always split things 50/50. I have recently gotten a promotion at work that has come with a payrise.

The raise is around £400 a month extra after tax, pension and student loan payments. I planned to save the majority and use the rest to buy myself things during the month or go on more dates etc.

My girlfriend mentioned me paying more of the bills. I reminded her of our agreement but she just said it wasn't fair that I wasn't paying more.

I pointed out she's being greedy for wanting to change out agreement just so if benefits her more. I said there was nothing unfair about our original agreement. Me getting a payrise doesn't affect her ability to pay her half.

She just said again I wasn't being fair and that I was out of line calling her greedy but I disagreed

AITA for calling my partner greedy for wanting to change our agreement so that it benefits her more
