My girlfriend broke up with me over a simple question about paying for dates -Am I in the wrong?

I’ve been dating my girlfriend for a while, and I’ve always enjoyed pampering her, treating her on dates, and paying for meals. But recently, I started feeling like I was always the one picking up the tab, and it made me feel unappreciated and like I was being taken advantage of.

So, I asked her, “Why is it that you never offer to pay on any of our dates?” I thought it was a simple, open question to understand her issue. I love doing nice things for my partner, but I also want to feel like my efforts are valued. Did I handle this poorly, or is there more to this than I’m seeing?

Has anyone else experienced something like this? Any advice on how to approach these kinds of issues in relationships?
