AITA for telling my girlfriend I don’t want to split bills 50/50 anymore?

I (28M) have been dating my girlfriend (27F) for almost two years. From the beginning, we agreed to split everything 50/50 – rent, groceries, dates, etc. I thought that was fair, even though I make significantly more than she does (I’m in tech, she’s a teacher).

Lately, I’ve started to feel weird about it. I cover some extras here and there (like vacations or bigger gifts), but the basic stuff is always split down the middle. The thing is, she’s clearly struggling financially, and I know she’s been dipping into her savings just to keep up.

I brought it up and said I don’t think we should do this strict 50/50 anymore, maybe something more proportional to income. Her reaction was not great. She said she doesn’t want to feel “kept” or “less independent”, and that she wants to be treated as an equal.

I get that, but isn’t real equality also being realistic with our situations? I don’t think I’m being manipulative or trying to control her, I just don’t think someone should go broke to maintain a split that only works on paper.

AITA for wanting to change the dynamic even though she didn’t ask me to?
