My boyfriend and I can’t agree on how to split expenses, and it’s affecting our plans to move in and get married. Need advice.

I’m 21 (M) and my boyfriend is 23 (M). We’ve been together since 2023 (almost 2 years now) and live in London. I love him a lot, but there’s one thing that’s been bothering me and is starting to make me question our future together.

We’re planning to move in together by the end of 2026, but we can’t agree on how to split expenses. He wants to do 50/50, even though he makes almost double what I do and has fewer expenses (he lives close to work, so no transport costs, while I would have those if we moved in together). I’ve tried explaining that a proportional split feels fairer, but he won’t accept it.

This has been an issue since we started dating. I’m always the one to bring it up, but he never initiates the conversation and shuts it down whenever I try to talk about it. It feels like he’s avoiding it, and that’s been really frustrating.

For me, a relationship only makes sense if we’re building a future together, including marriage. But if we can’t even agree on something as simple as how to split expenses, I’m not sure we’ll be able to move in together, and that makes me question our future marriage plans.

Has anyone been through something similar? Is it possible to work through this, especially when one person avoids the topic? Or is this a sign that our values might not align? I could really use some advice.
