Not nearly at 15 years here, but my partner and I have the same arrangement right now. We talked early about keeping finances separate. We have _fairly_ similar mindsets to spending and saving, which I think helps. I make a bit more for now, but don't end up going on super lavish vacations or events that the other person couldn't afford anyway. Most of my income is not directly accessible to me anyway as it is in my limited company, and I pay myself a very moderate salary. Sometimes I make up the difference if I want something that would stretch him too much financially. I'm pretty sure in a few years he'll be making way more money than me, and trust that he'd also remain considerate of each of our limits when it comes to how we arrange spending that affects both of us.
