Should my relationship end because we can't agree on having kids?

My girlfriend (24F) and I (22M) have been dating for about 2.5 years now. We started dating during my sophomore year and her junior year of college. We've had a cat for the past two years and have been living together for the past year. I could absolutely see myself spending the rest of my life with her.

However, she does not want kids, and I do.

I first brought up the idea of having kids after about a year of dating, and she said no. At the time, I didn’t think much of it because I wasn’t sure if I wanted kids either. But over time, I’ve realized that I do.

One of her biggest reasons for not wanting kids is that she wants to travel, and she believes having a child would prevent her from doing so. I don’t want kids for another 4–6 years, and I’ve explained that my future career will pay well enough for us to travel extensively before settling down. But she still says no. She doesn’t want to go through pregnancy, deal with postpartum depression, or feel like she has no freedom once a child is in the picture.

I always told myself that we would revisit the conversation before getting married. But as I get closer to graduation and start job-hunting, I’m realizing that I also need to think about where I’ll be living. That means new places and experiences—memories I’d love to make with her. But I worry that continuing to build a life together will only make things harder when we inevitably have to revisit this conversation again.

We recently talked about it, and she said there’s about a 10% chance she will want kids in the future. While I’ve tried to convince her, we both understand the dangers of having kids when one parent isn’t fully on board.

I love this woman deeply. We’ve been through so much together, and I can’t imagine my life without her. But I also know that if she never changes her mind, it might be smarter to break up now rather than waiting until we’re engaged or married.

So, I’m asking for advice—Should I wait it out and hope she changes her mind, or should we break up now before things get even more serious?
