AITA for asking my boyfriend to reconsider our 50/50 financial split after moving in together?

I (26F) have been dating my boyfriend (28M) for almost 2 years. We moved in together about 6 months ago. Before we moved in, we had separate places and generally split things when we went out (dinners, trips, etc.), which felt fair.

But now that we live together, I’ve started to notice how unbalanced things feel.

We split rent and bills 50/50, which on paper sounds fair. But I make significantly less than him, like, he’s in tech making nearly 3x what I make. I work in education. So 50% of my income is going toward rent, and for him it’s maybe like 15% or something… I’ve had to cut back on a lot (no more gym membership, barely going out), and meanwhile he just bought a PS5 and went on a weekend trip with his friends ?? 😭

I also end up doing more of the cooking, cleaning, groceries, laundry , not because he demands it, but because he just… doesn’t really do it unless I ask. I brought this up recently and he said I’m being unfair and trying to “change the rules” we agreed on when we moved in.

He says it’s not his fault I chose a lower-paying career, and that if we start doing things based on income, then “what’s next, keeping score on everything?”

I’m not saying he needs to pay all the rent or anything. I just think 50/50 isn’t always fair when one person makes so much more. My friends are kind of split, some agree with me, some say I knew what I was getting into and it’s not fair to expect him to pay more now. The only thing I’m asking is for my bf to realise and be considerate of the fact that half of my money is being spent on our rent, and try to find some sort of compromise or smth about this :/

So, AITA for wanting to stop splitting 50/50?

TLDR: My boyfriend and I split rent and bills 50/50, but he makes almost 3x what I do. I’m struggling while he’s super comfortable, and I also do more housework. I asked if we could reconsider the split, and he called me unfair. AITA for wanting to change it?
